SONY FX1000 - REVIEW

An Exclusive Hands-on Preview
By David Speranza



Reaffirming its commitment to the HDV format, Sony has announced its newest top-of-the-line prosumer camcorder, the HDR-FX1000. This model replaces the HDR-FX1 and adds a substantial number of improvements, including three Exmor-enhanced 1/3" CMOS sensors, a wide-angle 20x G-Series lens, and—in a welcome first from Sony's consumer division—24p/30p progressive scan recording. Other new features include increased low-light sensitivity (down to 1.5 lux), dedicated zoom, focus and iris rings, 3 built-in ND filters, and a 3.2" Xtra Fine LCD with an impressive 921K-pixel screen.
Having just laid our hands on a preproduction model, it seems safe to say that this camera delivers on more than specs alone. About half an inch shorter than the FX1, the FX1000 feels exceptionally solid and balanced, with a more professional and robust build than its predecessor in just about every respect. Any part of the FX1 that felt plastic-y or hollow seems to have been ruggedized, from the internal lens cover, which feels less toy-like, to the grooved top handle, the focus ring, the inset control buttons, and even the eyepiece hinge—it all just says "professional." For a camcorder that's technically a "consumer" model, that's pretty remarkable.
And while the lack of XLR inputs keeps this fixed-lens camera from full professional status, its street price of $3,199 is $500 less than the FX1 and less than half the price of the pro-level HVR-Z7U (which adds an interchangeable lens to an otherwise similar feature set). This makes the FX1000 an amazing package for independent videographers and filmmakers seeking broadcast-quality, 24p film-like imagery.
Along with introducing the FX1000 and discontinuing the FX1, Sony also plans to reintroduce its previously discontinued HDR-FX7, drastically cutting its price from $3,500 to $1,999. While an unusual move, this effectively diversifies the company's prosumer line by positioning the FX7 as a credible bridge between the more consumer-oriented HDR-HC9 and the now-flagship FX1000. At the same time it gives Canon's and Panasonic's comparable products more price-to-price and feature-to-feature competition. Aside from the XH-A1's XLR inputs, the FX1000 provides far more bang for the buck, its new specs giving it a substantial edge over arguably any sub-$4,000 camcorder out there.
With only a preproduction model at our disposal, we were unable to properly test the quality of video output, but let's see exactly what all those new specs mean.
Image Quality
In switching from the FX1's three 1/3" CCD imagers to new 1/3" ClearVid CMOS sensors, Sony included the Exmor technology used in their more recent flash memory and pro XDCAM EX cameras. Adding this on-sensor analog/digital conversion to three CMOS chips—each dedicated to its own color in the red/green/blue spectrum—provides several important benefits. First and foremost are sharper, more detailed images (along with an extended battery life due to the CMOS chips using less power). But even more significant for HD shooters, many of whom still miss the great low-light capabilities of standard-def workhorses like the VX2100 and PD170, is the FX1000's ability to accurately capture images down to 1.5 lux. This is twice the ability of the FX1, Z1U or Panasonic's HVX200 (all at 3 lux), and compares even more favorably to the FX7, VIU, and Canon's XH-A1 and GL2—rated at 4 lux. This greater light sensitivity seems mostly the result of the improved noise reduction afforded by Exmor processing, along with what Sony claims to be a 30% increase in dynamic range (bringing greater detail to the image's dark and light areas).

At the same time, the FX1000 is the first camcorder to come with Sony's new G-series 20x zoom lens, replacing the previously standard Carl Zeiss lenses. These high-performance lenses, originally made for Minolta/Sony D-SLR professional still cameras, offer improved optics (aspheric elements, a circular aperture, internal focus, extra-low dispersion glass) and were designed to match the camera's sensor and image processor more precisely.
This particular lens also brings something else to the table: a wider angle. Its 35mm-equivalent 29.5mm–590mm zoom range makes it easily the widest lens in the Sony line—topped only by the 28mm on Panasonic's new AG-HPX170 and AG-HMC150 (but wider than the Canon XH-A1's 32.5mm). This is a real boon to filmmakers needing to shoot in tight spaces, as it avoids the inconvenience, expense, and reduced image quality that comes with wide-angle converter lenses. Sony also seems to have carried over the digital extender from its FX7, which further magnifies the zoom by 1.5x with minimal quality loss.
x.v.Color technology is the final element in Sony's bag of improved imaging. This provides the images with a widened color range—nearly double that of standard RGB—and offers more natural color reproduction when displayed on an x.v.Color HDTV or monitor.
Film-Like 24p Progressive Scan
Unlike Canon and Panasonic, the cameras from Sony's consumer division have historically offered either HD or 24p, never both. The FX1000 breaks that mold, dropping the FX1's CineFrame mode for true progressive-scan 1080/24p and 30p—allowing budget-minded filmmakers and videographers to achieve the much-coveted "film" look. Two CinemaTone Gamma and CinemaTone Color settings are also available, which together enhance the 24p's film-like motion by creating deeper blacks and colors while maintaining detail in the middle tones and highlights. Although the FX1000 does not offer native progressive recording, its 24p/30p progressive modes (along with standard 1080/60i) go a long way toward giving Sony's HD customers the widened image palette that Canon and Panasonic users have taken for granted. For anyone who was on the fence about whether they could sacrifice 24p for the sake of brand loyalty, that decision no longer has to be made.
Improved Control
Both the FX1 and FX7 offered a healthy amount of control over the image coming through the lens. But the FX1000 ups the ante on the degree of professional control in camcorders at this price point. The most obvious change is the new iris ring, which joins the focus and zoom controls where it rightfully belongs—on the lens. This brings a more reliable, intuitive feel to image adjustment, especially for shooters used to working with higher-end cameras and lenses. Also added is a third built-in neutral density filter, making the FX1000 the first prosumer camera to offer 1/4, 1/16 and 1/64 ND settings, giving greater versatility when compensating for excess light. Retained from the FX1 are color bars (for professional color alignment) and zebra display (highlighting overexposed areas), now joined by a live histogram display—an exposure tool that measures the distribution of light and dark within an image.
But it's the FX1000's Xtra Fine LCD that redefines monitoring and playback at the prosumer level. At a resolution of 921K pixels—versus the norm of 250K—the new display is a real eye-opener. The image clarity and sharpness this resolution is capable of brings a dramatic improvement to the critical focusing needed for hi-def capture. At 3.2" it's a tad smaller than the FX1's 3.5", but what it loses in size it more than makes up for in clarity and viewing angles. The accompanying .45" Xtra Fine viewfinder is likewise a significant step up, from 252K pixels to 1,226K, while the very useful peaking function—which broadens edges in the viewfinder to assist in focusing—has also been retained.
The standard complement of manual controls also remains in place—gain, shutter and white balance adjustments—along with settings for color (mode/level/phase/depth), sharpening and knee point levels, all of which are especially useful in fine-tuning cinematic looks. Other notable features include Minus Auto Gain, 2:3 pull-down to 60i for editing, a Memory Stick slot for 1.2MP still image capture, Smooth Slow Record, and HDV/DV switchability. An improved button layout repositions several functions to better advantage, including a more prominent and easily accessed audio control and recessed placement beneath the tape mechanism.
The only thing missing, it seems, are the fixed end points and lens barrel markings found on the FX1's zoom ring—an unusual and seemingly unnecessary downgrade on a camera that's otherwise all about one-upmanship. But given the FX1000's added iris ring and the impressive responsiveness of all three servo-controlled rings, it's hardly a deal-breaker. Assuming the image quality is up to Sony's usual high standards, this camera—and its forthcoming professional counterpart—is going to make a lot of shooters very, very happy.
Bundling Vegas
In a related announcement, Sony is now bundling a special version of its Vegas Pro 8 editing software, specifically for its photo channel retailers, with its two most popular consumer HD camcorders, the HDV-format HDR-HC9VBDL and the hybrid 120GB HDD/Memory Stick HDR-SR12VBDL—providing a $500 value to filmmakers looking to take advantage of Vegas' intuitive and extremely robust interface. For those who have never used Vegas, this is definitely a smart way to spread the word on a great piece of software that deserves to find its way into more professional environments.
The HDR-FX1000 and newly priced FX7 are scheduled to ship in November, with the pro version of the FX1000, the HVR-Z5U, soon to follow. It will be interesting to see how video makers—and the competition—respond.

Panasonic AG-HMC150

Panasonic has announced the tapeless AG-HMC150 handheld camera, a competitively priced addition to the company's growing professional AVCHD product line that builds on the success of its popular DV-based AG-DVX100.

The AG-HMC150 provides enhanced HD production capabilities for budget-conscious operators desiring professional features, extended recording capability, and the fast, simple, and highly reliable workflow offered by tapeless, solid-state recording. The AG-HMC150 features three native 16:9 progressive 1/3-inch CCD imagers with an optical image stabilisation (OIS) function to ensure stable shooting and a 28mm Leica Dicomar wide-angle zoom lens (35mm equivalent). The AG-HMC150 handheld offers 1080i and 720p recording at 13 Mbps, comparable to current HDV compression formats with bit rates of 25Mbps. An additional, higher bit rate mode is incorporated for higher-level use. The AG-HMC150 supports a full range of HD formats including 1080/60i, 1080/50i, 1080/30p, 1080/25p, 1080/24p native, 720/60p, 720/50p, 720/30p, 720/25p, and 720/24p native and is 50Hz / 59.94Hz switchable.

The advanced handheld utilises the second-generation long GOP HD standard - AVCHD. Based on MPEG-4 AVC/H.264 high-profile encoding, AVCHD provides a near doubling of bandwidth efficiency and considerably improved video performance over the older MPEG-2 compression used in HDV formats. Announced by Panasonic and Sony, this industry-standard format is now supported by more than 30 companies and implemented in numerous camcorders, NLE systems, and consumer HD playback devices.




The AG-HMC150 offers professional HD performance with the simplicity of a digital still camera. And because the solid-state handheld camcorder records onto SD and SDHC memory cards, users can benefit from the reliability and random access of tapeless recording and capitalise on the cost advantages, widespread availability, and growing capacity of standard SD consumer cards. With the newly announced 32GB SDHC memory card and the camcorder's 6-Mbps recording mode, users can record up to 12-hours of HD video and audio on a single SD card.



"The AG-HMC150 is an exceptional camera combining leading-edge tapeless operation with a professional feature set at a very attractive price," said Carmen Mendoza, marketing general manager of Panasonic PBITS. "With the introduction of the AG-HMC151, Panasonic is making the enormous advantages of tapeless operation available to an even wider range of users."

Additional features of the AG-HMC150 include: professional XLR audio input connections; a wide range of data and signal interfaces including HDMI out, USB 2.0, component out (D-terminal), composite out and RCA audio out jacks; a 3.5-inch LCD monitor to display thumbnail images for quick viewing and playback; and a time code/user bits menu. The camera also has remote jacks for focus, iris and start/stop functions; a prerecord feature that allows the camera to capture footage occurring immediately before real-time recording begins; and a time/date stamp menu option for documentation purposes.

Panasonic's AVCHD camera line brings the benefits of solid-state recording to budget-conscious professionals. As with digital still photography, recording video onto SD/SDHC cards offers a fast and simple IT-compatible workflow with ultra-reliable performance and is resistance to shock, vibration, extreme temperatures, and weather. SD and SDHC memory cards are inexpensive, widely available, and can be reused repeatedly. As AVCHD records video as digital data files, content can be transferred and stored on affordable, high-capacity hard disk drives (HDD) and optical storage media - and transferred to future storage media as technology advances.

The AG-HMC150 will be available in the third quarter of 2008 at a price to be announced. More information is available at www.panasonic-broadcast.com

HPX170 Review

by Barry Green
The first functional HPX170 is now in the States, being prepped for its debut to the world at Chicago's HD Expo. I previously posted a "First Look" article that described all the physical/hardware changes that we could identify. Recently, I got a chance to spend a little time with the HPX170, next to the HVX200A. This is the first chance we've had to dig inside the menus and see what new goodies are offered or are in store.

DISCLAIMER: Just because it's talked about here, that doesn't mean it'll be in the production version! All camera manufacturers always say "features and specifications subject to change" and that applies here too. This is a preview of what we MAY get in the final version of the HPX170.

So, first, to revisit a few physical things: it's hard to describe just how ergonomically superior the HPX170 is, over the HVX200 (and embarrassingly superior for handheld work as compared to the reigning ergonomics nightmare, the EX1). The HPX170 really is about the size and weight of the DVX100; I even pulled out a DVX100 to compare. The HPX170 prototype is maybe half an inch longer, and half an inch taller, than the DVX100. And about the same weight. It's such a night-and-day experience, using an HPX170 handheld, vs. the HVX200 or EX1. There are subtle touches throughout, such as that you can open the LCD with one finger instead of as on the HVX200 where it takes pushing in a button and then manually pulling the LCD open. The power switch is a lot nicer, the buttons and switches have been a little re-organized to make things easier to find and more logically grouped, and the FOCUS-IRIS switch is probably the most pleasant surprise. (I'm on record as ragging on the silly FOCUS RING user-button feature of the HVX200, so I thought I'd think the FOCUS-IRIS switch on the HPX170 would be equally silly, but – I gotta tell you, you're gonna like it. More on that later.)

The HPX170 has the same absolute precision and repeatability to the focus ring as the HVX200 (thank you!) and the same manual zoom, it's got much better balance, it's thinner, it's way lighter, and its wide-angle field of view is significantly wider than the 200, and even somewhat wider than the 200A. And – oh, did I mention the LCD? Man, have they improved that! Now, it may be technically the same LCD panel, but it's so much improved that it's hard to describe. The image processing and EVF DTL are so enhanced that it's now very, very easy to know exactly when you're in focus. The HVX200A received some of this improvement but not as much as the HPX170. The HPX170 is so much better than the HVX200 in this regard that I say you really have to see it to believe it. Now, I didn't get a chance to take it outside to see how it performs in bright sunlight, but if it's a problem, that's what I've got a Hoodman for. Overall, I don't see the LCD as even being a problem anymore. It's seriously improved over the HVX200!

Other Physical Changes:

As mentioned in the First Look article, there's no s-video port, instead it has HD-SDI; the firewire port has been upgraded to a locking six-pin connector, and the SD card slot has moved to inside the P2 card compartment. In addition to HD-SDI there's a component video port, which uses a different connector; it uses a mini-D connector instead of the D-4. It's similar to, but not the same as, the connector used on the Sony EX1. It looks like the same basic design, but the Panasonic connector is bigger. Another change is that there's a new Slot Select button; instead of accessing SLOT SEL through a user button, it now has its own dedicated button on the back. The joystick from the DVX series is back, replacing the button pad of the HVX line. The thumbnail button is now called just "thumbnail" instead of audio dub/thumbnail. Obviously this is a change warranted by the disappearance of the tape deck; the "audio dub" function was only used for dubbing additional audio tracks onto the tape. Since the HPX170 has no tape deck, it has no need for the "audio dub" function. The HPX170 also doesn't have the gray and red VCR REC buttons. Instead, it repurposes the ZEBRA and OIS buttons to serve the same purpose. If you want to record an incoming firewire stream, you press and hold the ZEBRA and OIS buttons together (there's a text word and graphic saying "REC" over them to remind you). Or, you can use the remote control to trigger recording.

The RCA jacks, component video port, and SDI port are all output-only, no analog video input is possible. If you need to dub from external analog video devices, you'd need the HVX200A; the HPX170 can't do that. It can only input through the firewire (or the lens, of course).

The P2 eject buttons now are styled like those found on the HPX500 and the other larger P2 cameras, meaning that the buttons now fold over instead of just sticking out. The inside of the compartment basically looks like the inside of a P2 Gear's P2 compartment.
Okay, now, about that FOCUS/IRIS switch: the HVX200 had a similar kind of function, which was "FOCUS RING" that you could assign to a user button. This would determine whether the focus ring on the lens controlled focus OR iris. You could use that big ring on the lens to control your iris, but the drawback (and, dare I say it, the fatal flaw) of that arrangement is that it required you to be in autofocus mode. So that was of extremely limited value. Well, they fixed that on the HPX170: if you put that switch in IRIS mode, the ring works regardless of whether you're in autofocus or manual focus mode. After playing with it for a minute, I realized just how useful that is: if you put the camera in manual focus mode, and you put the switch in IRIS position, then you've done two things: you've DISABLED the focus ring, and you've gained a huge iris ring. Very useful for 35mm adapter users! Now you can forcibly lock the focus at one set position, and instead get a big huge iris ring. I bet this one feature alone is going to prove quite popular with 35mm adapter users.

The lens has a new focal length range, 3.9 to 51mm. In practical terms, the HVX200A is wider than the HVX200, and the HPX170 is wider than both of them. As for telephoto, the opposite is true: the HVX200 has the most reach, the HVX200A a little less, and the HPX170 a little less than both. The difference in wide angle is a lot more noticeable than the difference in telephoto though.

PERFORMANCE TESTING

My performance testing was limited because ... well, it's almost pointless, really. This is a development mule, not a finished product, so anything is subject to change between now and final production. It could be more sensitive or less sensitive, cleaner or noiser, more or less dynamic range, anything could happen. So I plinked around a tad and I'll report what I found, but understand that these findings are ONLY related to this pre-production model and may have no bearing on the final production models due in September.

Sensitivity: I tested it for general sensitivity as compared to the HVX200A. We already know that the HVX200A is about 500 ISO with very clean noise performance. The HPX170 uses the same chipset, so the assumption has been that it will have comparable performance, and my brief testing confirmed that yes, they are approximately the same. Which means that they're both a huge improvement over the HVX200 (when factoring in both more sensitivity and less noise).

Dynamic Range Testing: I used a top-of-the-line DSC DX1-72dB 13-step grayscale calibration chart. This chart is a backlit chart with 13 shades of gray, each designed to be precisely one stop brighter than the next. This type of chart is far more accurate than a front-lit chart and you can really tell whether you're seeing a difference in terms of each f-stop without any complications arising from reflections or improper lighting of the chart. It's not exactly a Stouffer 42-step chart (which shows you 14 stops in 1/3-stop increments) but it is a precisely calibrated 13-step backlit chart, definitely in the same class as the Stouffer.

I used Cinelike-D gamma, which affords the widest dynamic range. I also turned DRS (Dynamic Range Stretching) to OFF. DRS doesn't do much for a grayscale step chart, it's much more useful for real-world scenes. For chart purposes I stepped through the options and decided that turning DRS to OFF gave me the most realistic and useful readings for purposes of chart testing.

With this chart, the HPX170 could clearly distinguish 10, maybe 10 and a half stops of dynamic range. You can count the steps on a waveform monitor, and you can even more clearly see the stops being resolved on an actual HD monitor. What looks like potential crushed dark tones are actually easily distinguishable on the HD display. And while it's normal to see extra stops down in the dark zone that aren't really usable because they're noise-limited, on the 170 that really isn't much of a problem. The 170's noise is really low and quite clean, so you're not having to "rule out" stops because of too much noise.

But how much of an improvement is this, and how does a chart test translate to real-world performance? The 200A has this same sensitivity and same dynamic range, and represents an increase from the HVX200 mainly in terms of cleaner distinction between stops in the darker tones. But is this a real-world 10+ stops? That seems optimistic. As far as real-world: consider that while the RED ONE has been tested at 11 1/3 stops on a Stouffer, many real-world tests place its actual latitude at maybe 9 to 10 stops. Using that same model, while the HPX170 tests at 10+ stops, it probably delivers a real-world 8.5. I'll have to wait for a production unit and a chance to test it in real-world circumstances with my spotmeter to know what can be discerned outside of chart testing. As it is, I'm seeing maybe a half-stop to one-stop increase in usable dynamic range, mainly due to the lower noise allowing us to see into the shadows better. That's without DRS though – wait until you read about that little surprise...

SOFTWARE CHANGES

Most of the physical changes were reported previously in the First Look article, so the rest of this article is about the changes "under the hood", the new software changes. And frankly, as far as this article is concerned, that's where the party's at.

First, check out this little nicety: the thumbnail data display can be set to show clips by user clip name! How cool is that?
Of course, that's not all that cool unless you have user clip names assigned to your clips, right? On the HVX200/200A, that meant having to set the names in P2 Viewer and loading in through the SD card. Well, not anymore: on the HPX170, you have a software keyboard for entering metadata.
You can enter in-camera metadata, or you can enter per-clip metadata. That means you can set the metadata that will be automatically attached to all clips, or you can go into each clip and set the metadata for that particular clip. You can now basically change all the metadata, right in camera. (Of course, you can still load in metadata via the SD card too.)

All the buttons inside the LCD on an HVX200 are there on the HVX200A, but there are three new buttons: EVF DTL, WFM, and LCD. The EVF DTL button may have moved from the back of the HVX200, but that's not the big change: the big change is that it's now much stronger. The peaking is just wonderful. It's now incredibly easy to tell when something pops into sharp focus. On the HVX200/200A, the EVF DTL was tuned to be very mild, and it was one of those functions that you'd turn on and never disengage. But on the HPX170 the difference between on/off is huge. The improvement in EVF DTL alone should go a long way towards silencing critics who complain about the quality of the LCD panel. The LCD may be unchanged, but with the improvements in the focus assists and the EVF DTL, it's now much, much more usable. The HVX200A looks to have improved EVF DTL as well, but somehow it doesn't appear to be quite as strong as the HPX170's. Whatever they did, it works – the HPX170's LCD looks noticeably sharper than the HVX200A's and significantly better than the HVX200's. I would buy one just for the improvements in focus alone.

The WFM monitor button has already been talked about, as has the Vectorscope; we talked about those in the First Look article. The Waveform Monitor and Vectorscope only show up on the flip-out LCD, not on the viewfinder, which is very nice indeed: you can monitor the full frame on the VF, and monitor exposure/waveform on the flip-out LCD. That's exactly how we'd hoped it'd be done.

The LCD button is a programmable button, with three options: LCD REV, OVERSCAN, and LCD BL (backlight).

1) In LCD BL configuration, pressing the LCD button results in it cycling through three levels of brightness, so as you press it the LCD goes brightest-medium-darkest and then back to brightest.

2) In LCD REV mode, pressing the LCD button toggles between normal, and 180-degree rotated (for 35mm adapters). When in flipped mode all menu items are hidden, as are the waveform and vectorscope and, sadly, the focus assists too (at least, in this pre-release preproduction version). Only the LCD flips, the EVF does not, which is great: the menus are all displayed on the EVF regardless of the flip status. You do get the focus bar and the EVF DTL in the viewfinder, but nothing on the LCD.

3) OVERSCAN toggles between showing you the full frame, and showing you an overscanned image (such as is likely to be shown by most HDTV sets). On the HVX200 we had the option of displaying a 90% safe zone, with the idea being that anything outside that safe zone would probably be cut off on an HDTV. With the HPX170 you still have that option of using a 90% safe zone, but you also have the much more useful ability to actually toggle between underscan and overscan. The camera shows a slightly zoomed-in display, with a white frame outlining it, to show you exactly what's going to appear within the overscan area.

You can exit out of most of the thumbnail menus by pressing the "menu" button, you don't always have to go down to "exit". You can also go into or out of the clip properties window by pressing the DISP/MODE CHK button, which I found to be very, very useful. You can now get into a clip's properties with one button press, instead of having to go through the menu system to PROPERTY->CLIP PROPERTY.

For Focus Assist, there are four total ways to get assistance with focusing: there's the magnified window (which now stays on as long as you want; it doesn't time out anymore); there's the "peaking" (aka EVF DTL); there's the Histogram/Frequency Distribution graph that first debuted on the HPX500/HPX2000 cameras, and there's a new Focus Bar.
The Focus Bar is probably the simplest focus assist to use: as the shot becomes more in focus, the bar gets longer; the more out-of-focus you are, the bar grows shorter. Pretty simple, and works surprisingly well. You can individually control which focus assists show up in any combination.

Oh, and three of the four Focus Assists now work in Standard Def! You don't get the magnified window, but the histogram, the EVF DTL, and the focus bar all work even in standard def.

The Color Bars feature now also optionally outputs a -12dB audio test tone, for calibrating with an external mixer or audio recorder.

The HPX170 also has the ability to burn the time and/or date of the recording right into the footage. This opens up a whole new market, legal videography.
Oh, another nice little update is the CLIP COUNTER mode. On the HVX you can choose to see the timecode or a counter (which counts the # of seconds you've been shooting). On the HVX it counts the total # of seconds since the last time you re-set the counter. But on the HPX170, it can do that as well as automatically resetting to zero every time you start a new recording (your choice, you can have it either way).

There's also a one-stop MENU INIT button that resets all menu items and scene files back to factory default.

And, the LCD has a few selectable "safe zones" for 4:3, 13:9, 14:9, and 15:9. If you have to shoot for European television and protect for 14:9, well, now there's a cage generator. No 1.85:1 though, at least not on this preproduction unit.

Perhaps my favorite software/hardware change is when you're in P2 thumbnail mode, and you want to play back a clip, but the icon's number is in red (meaning, it was shot in a different format than the camera's currently set to). On the HVX200, that meant having to jump back to camera mode, going into the RECORDING SETUP mode, changing the recording format, then going back to the thumbnail mode. A little bit of a hassle. Well, I quickly found that on the HPX170 you don't have to do that, you can just turn the thumbnails off, bring up the menu, and change the recording mode there. What used to be a six or eight second process is now down to maybe two seconds, right? So I thought that was pretty cool until it was pointed out to me that you don't have to do that at all: you can change the playback mode right from the thumbnail screen. Just put the cursor over the clip you want to play, and hold the joystick down for a second, and it'll automatically swap to the right mode. This, my friends, is heavenly. You've got to see it to realize just how user-friendly it is. They've been listening! We thought this function was added at NAB but couldn't figure out how to make it work, but it's definitely functional now, and using it is just so addictive.

For image controls, all the same scene file settings are there, but there's a little bit more control in three areas:

1) MASTER PEDESTAL. On the HVX200/200A, you get a range of -15 to +15. On the HPX170 you get a range of -100 to +100. This means that not only do you get a tremendous amount more precision in your adjustability, but it also extends the range (i.e., -100 on the HPX170 is noticeably more crushed than -15 on an HVX, and +100 on the HPX170 is more raised than +15 on the HVX).

2) A.IRIS LEVEL: on the HVX you get a range of -4 to +4, on the HPX170 it ranges from -10 to +10. My quick evaluation shows that the HVX gave you control over about 1/3-stop increments, the HPX170 gives you control in about 1/6-stop increments.

3) COLOR TEMP is now split for Ach and Bch. That means you can set a different COLOR TEMP setting for each of your manual white balance channels; very cool.

Oh, and more frame rates! Did I forget to mention frame rates? There are now 20 frame rates instead of 11 as found on the HVX series. It still starts at 12, and ends at 60, but there are a lot more steps in-between. I don't know if the final list is set in stone so I'm not printing them here. I do know the question that many of you are asking though, and the answer is: I tested it, and yes, it worked. Heh.

Okay, and now for the biggie: the other image control they've added is DRS (Dynamic Range Stretching). This is basically an in-camera way to get High Dynamic Range images. It's a feature imported from the AJ-series HPX2000/HPX3000. This one feature greatly expands the appearance of dynamic range across the scene. I could attempt to describe what it does, but it's complex. Let me sum it up by saying that your shadows will be less harsh and your highlights won't blow out as easily, and then let me show you a few pictures:





DRS is very, very neat. It really appears to extend the dynamic range, compressing more tonal information into the scene. Unfortunately, it appears to be limited to 1080/60i mode only; I sure wish it was available in the 24P modes but something about the processing makes it limited to 1080/60i.

New user buttons:

1) D.ZOOM: Yes, this is a digital zoom feature. Don't know why we wanted that, but we got it. It magnifies the center of the image and ranges in steps from 2x to 5x to 10x. This feature is only available in 1080/60i mode, and also was inherited from the HPX2000. A digital zoom may not be all that useful for filmmaking purposes, but perhaps for newsgathering it would be handy (especially since it doesn't impact sensitivity, the way an optical doubler would; but it does degrade resolution).

2)LVL METER: This toggles the audio meter display between showing Channels 1 & 2, and showing Channels 3 & 4, so you can actually monitor the audio levels on 3 & 4 now!

3) LAST CLIP: This is the last-clip-delete function, and I figure I'll permanently glue this function onto one of my HPX170's user buttons. If you've just shot a clip you know you'll never use, pressing this button lets you delete it instantly.

4) PRE REC: This turns on (or turns off) pre-record mode. You can still do that in the menus, or you can now assign it to a user button.

5) F. RATE +, F. RATE -: these buttons let you change the frame rate you're shooting at. Can't change 'em during a take, but you can now change them inbetween takes without having to go into the SCENE FILE menus.

We lost the SLOT SEL user button, but that's no big loss since we now have a dedicated SLOT SEL button on the back of the camera.
The display has one more function to talk about: DOWNCON MODE. This function changes the way the downconverted SDTV display gets rendered. On the HVX200, when shooting high-def 16:9, the only way to see the downconverted video output was as a 16:9 squeezed image. On the HPX170 you now have the choice of sending out a 16:9 squeezed image, or an unsqueezed letterboxed 4:3 image, or as a center-extraction side cropped 4:3 image.
Oh, I also found a few new menu options in the thumbnail display:

1) EXCH. THUMBNAIL allows you to set a new thumbnail for a clip, right in-camera.

2) PLAYBACK RESUME (on/off): this is a choice as to how you want your clips to play back once you've stopped playback. In other words, if you're playing a clip and you stop playback, then when go to play that clip again it'll start over from the beginning. On the HPX170 you have the option of having it pick up where you left off and play back from there.

3) P2 CARD REMAIN lets you choose to show the available recording time as either ONE-CARD or TOTAL (both cards added together).

SUMMARY

I went back to Luis Caffesse's wishlist thread, where he was tracking all the requests that users had made for changes to be incorporated into the HVX's eventual successor. Most all of the changes that Panasonic implemented look to be direct responses to user requests. The HPX170 is now smaller, lighter, sleeker, wider-angle, cleaner noise, with more dynamic range, it's more sensitive, way better in low light, has more professional connectors (including SDI and a locking firewire port), more options (you can turn the built-in microphone off, and you can monitor the audio on channels 3 & 4, you have almost twice as many frame rates), more usable (much better ergonomics and greatly improved focusing off the LCD, software keyboard for metadata, shortcuts for deleting last clip and changing frame rate and pre-record mode, getting into and out of clip properties, and so many other nice little improvements.) In short, there are dozens of improvements across the board, in four main categories: ergonomics, connectivity, video performance, and ease of use. I look forward to testing the final version in September to see what else might have changed, but as it stands now, I will definitely be upgrading my HVX200 to an HPX170.

Fluxo de trabalho da Sony HVR-Z1

A guide to the various shooting formats, workflows and other Z1 shooting tips.
by Nigel Cooper


Shooting in the Past, the Present and the Future
This short tutorial is aimed at those who are used to shooting in standard definition DV or DVCAM on the Sony VX2100 and PD170 camcorders; but who have recently bought a Sony HVR-Z1E HDV camcorder. This guide is designed to introduce newcomers to the Z1, how to use the camera in standard DV, DVCAM and HDV modes and how your SD and HDV workflow will be affected - now and in the future. At the end I’ve added some shooting tips and other things to watch out for.

There is a very good reason that Sony has three shooting modes on the Z1. I suspect the most relevant one is that at the time of writing this tutorial, Blu-ray DVD players and HD TV sets are rare amongst general UK households. It is going to be a good few years before we start seeing HD DVD players in domestic households that can actually play back DVDs that have been authored from a native HDV 1080i project. In fact, I don’t think the first HD DVD player has even landed in the shops yet. So, what you have to decide is how you are going to use your Sony Z1 as a shooting acquisition format in the immediate future. Lucky for us the Z1 is backward compatible as well as future proof.


There are three options open to you with the Z1.

Option 1 - Shoot, Edit & Author DVD in Standard Def:
This first workflow involves shooting in standard def (DV or DVCAM), editing in standard def and authoring your DVD in standard def; this could be in either DV or DVCAM shooting mode. The advantage with this workflow is that you are used to it and everybody can watch your finished DVD on their current standard definition DVD players and TV sets. However, the disadvantage is that you will be stuck with a standard definition project as your original footage was shot in SD mode, hence it will not be future proof.

Option 2 - Shoot HDV, Edit & Author DVD in Standard Def:
The second workflow involves shooting in HDV, then down-converting to standard def from the Z1 as you import the footage into your NLE computer system, then editing in standard def and authoring your DVD in standard def; this could be either DV or DVCAM. The advantage with this workflow is that you can edit in a way that you are used to and everybody can watch your DVD on their current standard def DVD players and TV sets. Although your finished DVD will be standard def, you will have the option of re-importing your HDV footage in the future when more people own HD DVD players and HD TV sets. When that time comes, you will import your native HDV footage with no down-conversion from the Z1. You can then edit in native HDV, providing you have a NLE computer system and software package that can handle HDV. Then finally you can author your DVD in native HDV and burn a HD DVD ready for playback on domestic HD equipment.

Another advantage to shooting in HDV and then down-converting to SD from the Z1 and editing and authoring an SD DVD is that the picture quality is said to be an improvement over shooting in standard def to start with; why is this? By shooting in HDV you are effectively recording a lot more information; 1440x1080 pixels as opposed to the 720x576 pixels of standard def. Because you have more information on tape to start with, when you carry out the down-conversion to SD from the Z1 you end up with more information in your final standard def edited programme. DVD's that have been created from HDV footage are superior in image quality than DVD's originating from standard definition video as HDV provides more pixel data to work with, so there is less reduction in quality in the MPEG-3 transcoding process. You will find that DVD's produced from HDV originated footage look stunning.

Option 3 - Shoot, Edit & Author DVD in HDV:
The third workflow involves shooting in HDV, editing in HDV and authoring your DVD in HDV. This option has the advantage of maintaining the highest possible image quality throughout the entire production process from shooting, through editing and finally authoring and burning off your DVD. It is an easy workflow to get used to and is not much different from what you are used to in a standard def environment. Some advantages include: taking still images from the timeline of your HDV productions during editing to use as photos on say the DVD cover will be superior due to the larger pixel count, and if you have a high def computer monitor there is nothing quite like editing in HDV – the quality is simply stunning. However, you will need to upgrade your NLE computer editing system to accommodate HDV, this will mean a lot more RAM, faster processing power and possibly new or updated software. The only major concern with the total HDV workflow is that your client and the viewing public will not be able to view your HDV-made DVDs until HD DVD players and HD TV sets are more commonplace; unless of course they own an Apple Macintosh computer with a DVD drive, in which case they can view your HD DVD using Apples built in DVD player software.
Setting up the various shooting modes on the Z1


Shooting in the Past, the Present and the Future

1: Standard Def 720x576 PAL 50i DV shooting mode.
The first option we will look at is for shooting in standard definition 720x576 PAL in regular DV mode. This is relatively straightforward and your workflow won’t be any different to what you are used to with your Sony VX2100 (or other Mini-DV camcorder).

To shoot in standard DV mode on the Z1 press the ‘MENU’ button on the rear of the camera, then scroll down to the ‘IN/OUT REC’ menu and press the ‘SEL/PUSH EXEC’ button to select it. With ‘REC FORMAT’ highlighted press the ‘SEL/PUSH EXEC’ button to enter its sub-menu, then using the scroll wheel select ‘DV’ and press the ‘SEL/PUSH EXEC’ button to enter that setting. You will now be returned to the previous screen. Scroll down to ‘REC MODE’, select it and choose ‘DV SP’ from the menu then press the SEL/PUSH EXEC’ button again to enter the setting. Then exit the menu.

2: Standard Def 720x576 PAL 50i DVCAM shooting mode.
The second shooting option is standard def DVCAM mode. The advantage of DVCAM over standard DV is basically down to tape speed and ‘track pitch’. It’s worth noting that if you use a standard 60-minute Mini-DV cassette in DVCAM mode, it will only give you 40 minutes of recording time, this is because the tape transport speed of the DVCAM format is 1/3rd faster than Mini-DV, which brings us to the next major difference between Mini-DV and DVCAM, ‘track pitch’. The DVCAM format has a track pitch of 15 microns whilst Mini-DV has a track pitch of just 10 microns. To give you an idea of how wide a micron is, a human hair is approximately 60 microns thick, so as you can imagine these tracks on the tape are incredibly small.

Basically track pitch is the width of recorded information on the tape. Because the tape transport speed is faster DVCAM mode the track pitch is wider, this yields a more durable tape system, for example in the edit suite footage shot in DVCAM mode will be able to withstand being thrashed back and forth in a deck as you shuttle around looking for specific clips on your tapes or whilst you mark all the in and out points ready for a batch capture, there’s also less chance of dropped frames, 50% fewer visual dropouts and artefacts. If you are used to using a Sony PD170 (or other Sony DVCAM camcorder) then your workflow will be no different.

To shoot in DVCAM mode on the Z1 press the ‘MENU’ button on the rear of the camera, then scroll down to the ‘IN/OUT REC’ menu and press the ‘SEL/PUSH EXEC’ button to select it. With ‘REC FORMAT’ highlighted press the ‘SEL/PUSH EXEC’ button to enter its sub-menu, then scroll down to ‘DVCAM’ and press the ‘SEL/PUSH EXEC’ to enter that setting. You will now be returned to the previous screen. Now scroll down to ‘REC MODE’, select it and choose ‘DVCAM’ from the menu then press the ‘SEL/PUSH EXEC’ button again to enter the setting. Then exit the menu.

3: High Def 1440x1080 PAL 1080i HDV shooting mode.
The third shooting option is the high def HDV 1080i shooting mode. If you are used to using a standard Mini-DV camcorder such as the VX2100 or any Sony DVCAM camcorder then your workflow is about to change slightly.

To shoot in HDV mode on the Z1 press the ‘MENU’ button on the rear of the camera, then scroll down to the ‘IN/OUT REC’ menu and press the ‘SEL/PUSH EXEC’ button to select it. With ‘REC FORMAT’ highlighted press the ‘SEL/PUSH EXEC’ button to enter its sub-menu, then scroll to ‘HDV1080i and press the ‘SEL/PUSH EXEC’ to enter that setting. Then exit the menu.

To shoot in HDV 1080i mode it’s not actually that much more complicated; well not at the shooting stage anyway. When it comes to editing, things are a little different; you will have to refer to your NLE software instructions for this part and you might have to upgrade your hardware and/or software to a later version that can handle native HDV 1080i footage.

Down-converting to SD from HDV:
If you have shot footage in HDV mode and intend editing in standard def then you will need to down-convert your HDV footage to standard def as you import it into your NLE computer system. To do this you will have to make a few tiny adjustments in the Z1’s menu.

Press the ‘MENU’ button on the rear of your Z1, scroll down to the ‘IN/OUT REC’ option and select it by pressing the ‘SEL/PUSH EXEC’. Then scroll down to ‘i LINK CONV’ and press the ‘SEL/PUSH EXEC’ button to enter into the menu. With ‘HDV-DV CONV’ selected press the ‘SEL/PUSH EXEC’ to enter the menu and select the ‘ON’ option then press the ‘SEL/PUSH EXEC’ again to save this setting. You will now be returned to the previous menu. Scroll down to the ‘DOWN CONVERT’ option and press the ‘SEL/PUSH EXEC’ button to enter the menu and choose ‘SQUEEZE’ if you want to down-convert for editing in native 16:9 widescreen mode for final viewing on a widescreen TV set. Choose ‘LETTER BOX’ for editing for final output to 4:3 TV sets with letter-boxing appearing at the top and bottom of your 4:3 TV screen, but retaining the 16:9 widescreen format across the central part of the screen. Choose ‘EDGE CROP’ for editing for final output to 4:3 TV sets, but with the right and left hand edges cut off to fit 4:3 TV screens.


Z1 shooting tips and things to watch out for!

There are a few things that you will need to be aware of with the Z1. If you are new to the Z1 and are not aware of them your footage might not be as good as it could be; read on.

Zebra Setting:
The first thing I would recommend doing is going into the Z1’s menus and changing the ‘Zebra’ setting from its default 100, otherwise it will be difficult to spot ‘burn’ on the Z1’s LCD screen when trying to judge exposure. This needs to be set to something more workable and realistic. I would recommend setting this to 70, or 85 if you are used to a Sony DSR500/570/400 camcorder.

Date Record:
In the menu there is a setting called ‘DATE REC’. By default it should be set to the ‘OFF’ position, but you should check to make sure it is ‘OFF’. If this menu setting gets inadvertently changed to the ‘ON’ position the time and date will be permanently burnt into your footage, rendering it unusable for anything more serious than holiday footage.

Auto Mode:
Use this mode only when image quality is not important, such as the recce of a potential shooting location or covert shooting. Otherwise, for the best quality footage set the ‘AUTO LOCK’ switch on the left-side of the Z1 to the middle position. Which brings me nicely onto the next VERY IMPORTANT part, ‘Exposure’. Read on.

Exposure:
The Z1’s exposure system causes a great deal of confusion for many. In very bright or very dark shooting environments it can adversely affect the quality of the footage. The camera will not allow you to adjust the exposure manually by adjusting the chrome iris control dial on the front-left of the camera; instead it will fight against you by using the electronic shutter, or worse still, the electronic gain.

Here is how you prevent this from happening and maintain superior quality footage. First, you must manually set the Z1’s gain to 0dB and the shutter speed to 50. To do this, press the ‘GAIN’ button on the left-side of the camera to switch the gain into manual mode, then move the little chrome gain lever to the ‘low’ (L) position. 0dB will be displayed on the LCD screen. Next press the ‘SHUTTER SPEED’ button on the left-side of the camera and set it to 50 (the default for UK PAL) using the scroll wheel on the back of the camera. The shutter speed of 50 and the gain of 0dB will be displayed on the LCD screen. It is very important to keep both these settings displayed on the LCD screen AT ALL TIMES. If you don’t, you won’t be able to make any manual adjustments to the exposure using the chrome iris wheel. If you try to make any manual iris adjustments when the shutter and gain are not displayed on the LCD screen the camera will simply compensate for your so-called manual adjustments by changing the shutter speed and/or increasing the gain electronically, which will lead to either unsightly grainy images or an annoying strobe-like flickering effect.

Focus:
For the best results it is ALWAYS best to set the ‘FOCUS’ control on the left-side of the camera to ‘MAN’ (manual), then when you need to focus press the ‘PUSH AUTO’ button just underneath it. This will totally eliminate any ‘focus hunt’ problems as the camera tries to automatically focus on a moving object that is in the same frame as your actual subject.


Expanded Focus:
To further aid you with focusing you can also use the ‘EXPANDED FOCUS’ button next to the zoom rocker switch on the lens. When you press this button the central part of the image will be greatly enlarged on the LCD screen for 5 seconds, before the camera returns the display to normal; this is more than enough time to check your focus.

White Balance:
A quick tip for the white balance settings on the Z1 is to set the A and B memories for the indoor and outdoor environment of your particular shooting location. Doing this will speed up your daily shooting schedule as you switch from A to B as you move from indoors to outdoors or vice versa. But remember, when shooting outdoors the colour temperature will change as the sun gets lower in the sky so you might need to take another white balance reading every couple of hours or so.

Sony PMW-EX3 Review

Sony go after the low-budget independent filmmaker and wildlife filmmaker markets with the all-new PMW-EX3 solid-state interchangeable lens camcorder. Nigel Cooper spends the day with one in Belgium.

INTRO
It is no secret that I’m a massive fan of Sony’s XDCAM HD Optical Disc System and the SxS system. I personally own an F350 and have spent 4 months using an EX1 solid-state camcorder too. This review is not going to be incredibly long or extensive, simply because I’ve already done a very extensive review on the PMW-EX1 (see under the camcorder reviews section). The PMW-EX3 is the latest addition to the EX family, and it is basically an EX1, only in a new semi-shoulder mount design and with ‘EX-Mount’ half-inch interchangeable lenses. So for this review I’m basically going to concentrate on the differences between the smaller EX1 and this new EX3.

The PMW-EX3 uses all the same components as the PMW-EX1; same 1920x1080 half-inch CMOS chips, same circuitry, same 35mbps codec, same features. So the picture quality from the PMW-EX3 is identical in every way to pictures taken using the PMW-EX1. If you want to read more about the image quality of these EX series camcorders, read my comprehensive review on the EX1.

NEW SHAPE
The first thing you will notice about the PMW-EX3 is its shape. People (myself included) are comparing the shape to that of Canon’s famous XL series camcorders, with the wedge/chainsaw ergonomics at the back end. Sony has designed the camera in this way to help make shooting more comfortable. Due to the extra weight of this camera, as well as the extra weight of larger lenses, it has been designed and shaped as a ‘semi-shoulder’ mount camcorder, just like Canon’s XL H1. The EX3’s extendable shoulder rest sits at the front/top of your shoulder. This makes holding the camera much easier than the ‘out front’ method you would use with a Z1 or EX1. It takes away a bit of the weight, though you still have to firmly support the camcorder with your right hand. It also aids in stabilizing the camcorder too as it is not being held in mid-air. The shoulder rest/pad can be extended away from the EX3’s body by about 1.5”, this is done by pushing in a small metal device on the base of the camera toward the back. Once out, it locks in place. To push back in, simply push the metal device in again on the base of the camera.



Overall I found the semi-shoulder mount system of the EX3 to be much better than the Z1, EX1 ‘out in front’ design. Weight is better distributed and stabilization is greatly improved. However, I found my right forearm to be angled back at an angle so my hand was almost touching my shoulder. This felt a bit uncomfortable for me, but this is probably because I’m used to a full-size shoulder-mount camcorder were your forearm is more vertical. It’s been a while since I owned a Canon XL1 so I can’t comment on how they compare. But from my vague memories I think they are roughly the same.



UP YOUR NOSE
If you have never heard of the ‘up the nose’ look, you are about to be educated. We’ve all seen the 6-oclock news on the box. How many times have you seen a pack of journalists and cameramen flock towards the exterior courtroom steps on the street to get an interview with some famous, or infamous… probably hundreds. The camcorders used for these ENG events vary, Sony’s DSR570 and DSR450 are favourites, and at the low-end of the spectrum Sony’s HDV Z1 camcorder is even being used on occasion. When watching these news stories, it is blatantly obvious which shots were done on a Z1 (or other similar ‘out in front’ style hand-held camcorder). This is because most Z1 type shots suffer from what is known as an ‘up-the-nose’ look, when used in ENG shooting situations. Because the Z1 is a hand-held camcorder, cameramen often make the mistake of holding it at chest height when doing reporting jobs hand-held, this results in the up-the-nose look due to the camcorder not being on the ‘eye-level’ of the person being filmed, instead, because of the slightly lower shooting angle, the lens is looking slightly up the subjects nose, which looks amateurish, and just plain bad from a compositional point of view.



The reason for this short lecture in ENG journalism, is simply to let you know that the new PMW-EX3 does not suffer from ‘up-the-nose’ compositions, due to the fact that it is not held at chest height, instead, it is at the same level as full-size professional shoulder-mount camcorders so you are on the same eye-line when filming people in a standing position. So not only is the EX3’s image quality good enough for ENG broadcast, but the compositions are too.

INTERCHANGEABLE LENSES
We all know that the EX1 has fixed built in lens like the PD170 and Z1 models. The EX3 is the first EX series camcorder to feature an interchangeable lens system. Sony is calling this new half-inch mount the ‘EX-Mount’. Although it is half-inch, it is not the same half-inch mount that Sony’s full-size XDCAM camcorders use; however, Sony are including a half-inch B4 mount adaptor with the EX3 so you can still use professional half-inch lenses from full size half inch XDCAM camcorders if you choose. The EX3 comes with a standard lens, this is basically the same as the lens that is built into the EX1, only with the new EX-Mount on the back so it is interchangeable.



Sony has informed me that Fujinon are going to be manufacturing a wide-angle zoom lens in the dedicated EX-Mount specifically for the EX3. This will be good for corporate videographers and wedding videographers who often need to film in confined spaces.

35mm lens adaptor manufacturer Letus, are also making an adaptor to allow their Letus Extreme 35mm lens adaptor to be fitted directly onto the EX3 bypassing the lens altogether. This means the picture quality will be superior, as it will only be using the 35mm lens fitted to the front of the Letus Extreme.



So why would you need a camcorder with interchangeable lenses, as opposed to a built in lens like the EX1?

The chances are if you are a corporate or wedding videographer, or just a keen hobbyist, the chances are that you will be happy with the built in zoom lens of the EX1. However, if you are an independent feature filmmaker, or a wildlife videographer, or even a corporate or event videographer who wants variation, the interchangeable lens system will be indispensable. Independent feature filmmakers will need to use 35mm lenses for depth-of-field purposes, whilst wildlife filmmakers will need long telephoto lenses.

You will need to ask yourself what kind of productions you do and if you need extra wide-angle or extreme telephoto lenses, or 35mm lenses. If the answer is no and you are happy with a standard zoom lens, then save yourself £1,500 and buy an EX1 with a tripod and some lighting equipment instead. Or perhaps you will like some of the other features that the EX3 has over the EX1. There is a little bit more to the EX3 than just the interchangeable lens system; read on.

VIEWFINDER
Apart from the interchangeable lenses, the second most important thing you will notice about the EX3 is the viewfinder. Sony has decided to ditch the somewhat questionable quality viewfinder from the EX1 and do an incredible Monocular viewfinder conversion job to the LCD screen instead. The LCD screen on the EX3 is identical to the superb LCD screen on the EX1, only this one has a special coating on it to improve the viewing image quality even further when it is being viewed through the monocular lens. This design is what Canon use on their famous XL series, only Canon’s screen is microscopic in comparison and the resolution on the XL viewfinder is nowhere near that of the EX3, in fact the EX3 viewfinder is in a different league altogether. Sony has done what Canon should have done many moons ago.

When you flip the monocular lens out of the way the EX3’s LCD viewfinder can be viewed just like the fold-out LCD screen on the smaller EX1. The quality is just as superb and unlike most other fold-out LCD screens, this one CAN be used to adjust focus and even exposure. I found that viewing the LCD screen directly (not through monocular lens) it is good enough for focusing purposes, and you can press the ‘expanded focus’ button on the handgrip to aid further. The expanded focus option zooms in on the image on the LCD screen and stays zoomed for 5 seconds to allow critical focusing. It only zooms on the LCD, and does not affect the recorded image. After 5 seconds the LCD image reverts back to normal automatically, or you can press the button again before the 5 seconds are up to revert to normal beforehand. For the record, the monocular can be totally removed, as well as being flipped up and out of the way. You can even get a good idea of ‘white balance’ using the LCD also, not for critical white balance, but for a general check it is fine.


vWhen you flip the monocular lens down in front of the LCD you can then put your eye up to it just like a regular viewfinder. Viewing this way has to be seen to be believed, it is incredibly sharp and seriously high-definition. If you think the LCD screen looks great when viewed naked, the monocular takes it one step further, if that is possible, adding that extra ‘je ne sais quoi’.




Checking exposure on this new LCD/Viewfinder is also very possible indeed, something that was not really possible (not for serious applications anyway) in the past with LCD screens. The EX3’s LCD screen can be viewed from various angles with little change in contrast and brightness, making it ideal for setting/adjusting exposure. The EX3 (like the EX1) also has an exposure histogram that can be turned on/off. It shows up at the bottom/right corner of the LCD screen and can be used to aid when adjusting the exposure. The histogram works incredibly well. You aim to get the spike in the exposure to the general middle position as a rule of thumb, depending on the light. You will get used to how the histogram works after a few hours of shooting.

Another great feature of this newly designed viewfinder on the EX3 is that it has dials on the front for Peaking, Contrast and Brightness, as well as a Mirror Image switch, Display Batt Info and a Zebra switch. This design is more in keeping with that of a full-size professional viewfinder. Because of this, setting up and calibrating the viewfinder to ‘Bars’ is easy.

FRAME-RATE DIAL
We all know that the EX1 has an overcrank/undercrank variable frame-rate feature for slow and quick motion, but it has to be accessed via the menus, which can be time-consuming, and a bit of a pain if (like me) you use it all the time. The new EX3 has moved this feature out of the menus, and directly onto the body by means of a push button dial. Now all you have to do to change the frame-rate is simply push and hold the Frame dial in for 3 seconds (the 3-second system is done for safety reasons, in case you press it accidently), it will then light up with a funky blue ring light around it to inform you that you are now in variable frame-rate mode. Then it is simply a case of turning the dial and setting the frame-rate as desired, the frame-rate is displayed and can be checked via the LCD screen display. Like the EX1, the EX3’s variable frame-rate can be set from 1 frame to 60 frames per second in 720p mode, or from 1 to 30 frames per second in 1080p mode. The Frame dial cannot do ‘frame cranking’ like a proper film camera, that would be asking just a little too much, and it would probably put Super16mm film camera manufacturers out of business too.

OTHER DIFFERENCES
Apart from the semi-shoulder shape design, interchangeable lenses, new superb viewfinder design and variable frame-rate dial on the outside, there are a few other little differences also.

The audio dials have a plastic door cover, which prevents accidental change in audio levels. Other features over the EX1 include professional BNC connectors for timecode in/out and genlock in, as well as the usual HD/SDI out. There is also an 8-pin connector for studio operation camera contro. You can adjust shutter for instance, but no focus or zoom control (lens control is undertaken on the Fujinon lens connector as per the EX1). This 8-pin studio connector is meant for camera engineers to use in conjunction with a camera op, it does not have 'VTR' control though. this controls many features of the lens such as exposure and white balance etc. The rear end of the EX3 looks much more professional due to all these BNC connectors, as opposed to the rather bland rear end of the EX1. Other connectors have been moved to the side of the camera. The SEL/SET push/dial and the CANCEL button have been moved from the back and put in a more convenient place on the left side. The PICTURE PROFILE and CAMERA/OFF/MEDIA buttons have also been moved from the rear end of the camera to the left side. With the STATUS and MENU button also along this same row on the left side, all related buttons/dials are now on the same side of the camera making operation less fiddly than the EX1.



On the right side of the EX3 we now have a BNC MONITOR OUT, an S-video output connector and phono outputs for AUDIO OUT CH-1 and CH-2, as well as a COMPONENT OUT and USB; the latter is now very easy to get to, unlike the EX1, which requires some rather awkward fiddling around under the hand grip. The audio select inputs and audio level dials on the side of the camera also gives the EX3 a more professional feel. This makes the EX3 the most versatile HD camcorder in its class.



There is also an additional hotshoe mount to the rear of the handle of the EX3, as well as the one on top of the built in stereo mic. The rear one is designed for the PHU-60K SxS Professional 60GB HardDisc Recorder. While I’m talking about the PHU-60K hard disc recorder, I’ll also mention that the SxS card door works in a slightly different way to the one on the EX1. To open it you have to push it up a few millimeters, then open it out like a door on hinges; as opposed to the slide-only door on the EX1. This has been designed with the PHU-60K in mind, as the PHU-60K hard drive plugs directly into the rear card slot B.








BUILD QUALITY

I was surprised at how light the EX3 actually is. I thought it would be considerably heavier than the EX1, but it is only slightly heavier. The overall build quality of the EX3 is identical to the EX1. It is not as robust as the Canon XL H1, which for me is one of the better-built prosumer camcorders out there. The EX3 also doesn’t feel as solid and chunky as JVC’s ProHD camcorders such as the GY-HD111E. Both the Canon and JVC models are more ‘metal’ in build and feel, you can clearly see and feel the metal construction. The EX1 and EX3 on the other hand look and feel plasticky in comparison with no metal (externally at least, internally is a di-cast aluminum chassis) in sight. If the Canon XL H1 and JVC GY-HD111E produced the same image quality of the EX1 and EX3 I’d recommend them over the Sony’s any day, but sadly they don’t.

Having said that, it is no worse than Sony’s own Z1 or Panasonic’s HVX200. But if Canon and JVC can do it, why can’t Sony and Panasonic; after all, Sony and Panasonic are the leaders in the Broadcast sector. Considering that the EX3 comes out of the same factory as Sony’s professional DigiBeta models, I would have expected a little bit more in the way of external metal parts and overall build quality. That said, you don’t hear of that many broken Z1’s, so I’m sure there won’t be any issues with the EX1 or EX3 models in years to come. Like the EX1, the EX3 is built around a tough di-cast aluminum chassis so there should be no real problems using it in the field. I must confess to being the fussiest guy on the planet when it comes to build quality. If I pay £6,000 for a camcorder, I expect it to feel just a little bit more substantial than a Fisher-Price toy (though as any parent will know, Fisher-Price toys are indestructible and are made out of very good quality tough plastic; they just don't break). This is one reason I prefer my F350 XDCAM camcorder. Although the picture quality of the F350 and the EX3 are identical, at least when you pick up an F350 it feels like a serious piece of kit and you are inspired to get down to some serious shooting. Whenever I pick up a ‘Z1-type-Plasticam’ camcorder, it all feels very lack-lustre to me and I’d rather go back to bed.



If you own a PD170, VX2100, Z1 or a HVX200, you will feel right at home with the build quality of the EX1 and EX3, like I said, I’m just a fussy bugger.

NOT SO GOOD BITS
Although Sony has informed me that the Camera/Off/Media switch has been redesigned, it is still just as fiddly to use as on the smaller EX1 i.e it is too easy to turn the camera into Media mode when you think you have turned the camera off. The same applies to the ND switch on the camera body. Trying to set it to position 1 is a nightmare, it flicks straight past the 1 position into position 2, you have to grip it with your fingernails and try and ‘nurse’ it into the middle position. My tip here is to not cut your thumb and index fingernails for two weeks before a shoot; you’ll need them. The SEL/SET wheel is still way too small and sunk back into the camcorder’s body, making it difficult/fiddly to scroll through the menus; I’d much prefer to see a dial more like the ones Canon use on their EOS 40D and EOS 5D digital stills cameras. Most of the controls (with the FRAME dial being the exception) are too small and tricky to use; the words ‘Magnifying Glass’ and ‘Tweezers’ spring to mind with regard to some of the tiny switches; AUDIO SELECT switches for example. As for the BARS/CAM and PICTURE PROFILE buttons, you almost need a pen or pencil tip to push these buttons; that is how tiny they are. The ASSIGN 4 button is still impossible to find and use by touch, you have to flip the camera upside-down with the base towards you and lens pointing skywards; very awkward indeed, especially when there is in fact enough room to put this button next to the other 3, where it would make more sense. Finally, the buttons for ejecting the SxS cards are just too small and they don’t pop out enough. Again, you almost need the tip of a pen to eject the cards. Even when the SxS card does partially eject, it’s only by about 4mm, so you almost need a pare of tweezers to grab the tiny bit of card that is sticking out to be able to remove it, I often found that when trying to grab the SxS cards, I accidently pushed them back in by mistake.

SUMMING UP
At £5,995 inc vat the PMW-EX3 represents incredible value for money in terms of the superb image quality it produces, the same can’t really be said of the overall plasticky feel to the camera. When you pick it up, it doesn’t feel like you are holding a piece of kit that cost £6,000. If superb image quality for ‘full’ broadcast applications is what you are after, the EX3 makes the grade with ease. In fact the EX1 and EX3 are the only camcorders in their class (compact non-shoulder) that actually meet full broadcast requirements. Unlike the HDV format which can only be used for ‘no more than 30% of the total programme length using approved HDV camcorders, maximum 1 minute contiguous footage’ with Discovery HD (Silver Level) for example, the EX1 and EX3 can be used for 100% of the coverage of the programme (after some acceptance trials for Discovery the EX1 is accepted as Silver). This is a first for a camcorder of this small size and price.
