Sony threw the gauntlet at Canon, Nikon, and other camera manufacturers on August 24, 2011 when it showcased four new camera models– the SLT-a77, SLT-a65, NEX-7, and the NEX-5N. (Wait! Wasn’t it only two months ago that the photo world was introduced to two other Sony interchangeable-lens cameras, the SLT-a35 and the NEX-C3? Yep! Apparently, Sony is on a roll this year, introducing nearly as many interchangeable lens camera models as the combined total introduced by Canon, Nikon, Panasonic, Olympus, and Samsung.
All of the newest Sony models boast dramatic improvements or extraordinary features, but my two favorites are definitely the SLT-a77 and SLT-a65. Both of these are “SLR” style cameras featuring Sony’s Translucent Mirror Technology instead of a reflex mirror as found on true HDSLRs. The main advantages to using Translucent Mirror technology is to provide fast autofocus in live view and video modes, plus a smaller overall design.This promise they fulfill, and they also bring the highest resolution APS-C sensor into the race, a 24.3MP Sony Exmor that is also capable of recording FUll HD 10p video at 60p. More remarkable is the 2.4 million dot OLED microdisplay viewfinder that has higher resolution, more accurate color, and better responsiveness than any other microdisplay or EVF (electronic viewfinder).

First Look at Sony SLT-a77 and SLT-a65

INTRODUCTION:
One of the most exciting and challenging photo projects I’ve ever tackled took place in Sept. 2009 while on assignment for UNESCO’s World Heritage Photo Project. The week I spent diving and exploring the Great Barrier Reef was an incredible experience that I’ll never forget, and one that I strived to capture with the images, stories, and HD videos I brought back with me. But as the project progressed, I began to wonder: how could I share the awe-inspiring beauty of the reef and the fascinating creatures that dwell there with an audience that wants more than a digital slide show?

Want to learn more about the features and failings of the latest HD SLRs–especially in when it comes to recording video? If you haven’t already shelled out top dollars for a pro-level HD SLR, there might be solid reasons for choosing an advanced or semi-pro model for your HD video needs. But don’t just take my word for it, take it from the June, 2011 issue of Digital Photo Pro magazine!

The Panasonic Lumix GH1, while one of the most compact and advanced cameras in its class, can’t be submerged in water or safely used in the rain since it lacks waterproof seals. So, like many DSLRs or compact camera, it requires a fully waterproof housing to keep it safe and dry during dives. These  housings are fairly expensive, in many cases costing thousands of dollars more than the camera it protects, and must be designed not only to keep the camera safe under extremely high pressures (typically down to 100 feet or more), but also to allow the diver access to exposure, shutter, focus, and zoom controls. While several camera manufacturers routinely introduce compact digital cameras with a branded waterproof housing, it usually takes several months for underwater housing manufacturers to release a housing for a new DSLR model. The exception is Olympus, which routinely offers UW housings for its new DSLR cameras when they’re introduced or within a short period of time. The reason housings take so long to get to market is that the housing manufacturer needs an actual camera body and lens in order to design the housing to fit, and most camera manufacturers are unwilling to release their new models to any outside “accessory” company before the actual product launch–or even in the first wave of production models.

In order for my shoot on the Great Barrier Reef to take place in September, 2009, only a few months after the Panasonic Lumix GH1 was announced and just weeks after the first units reached stores in the US, I need help from the Lumix team in Japan. Fortunately, they had developed a relationship with the Proof housing company (also located in Japan) which had built an underwater housing for the Lumix G1 in 2008. So when my two GH1′s arrived from Japan in early July, 2009, a custom underwater housing and two lens ports were included in the shipment.

Unfortunately, it was up to me to provide underwater flash and video lights that would allow me to shoot underwater at depths below 10 feet, where most of the red light in the spectrum has been filtered out by the ocean water. Of course, lights were also necessary for me to shoot during during night dives or to capture creatures hiding in caves. The problem right off the bat is that Panasonic doesn’t manufacture its own waterproof flash or video lights, and I wanted to put together a system that was lightweight and extremely portable. The photo below shows you what I came up with:

The setup above includes two INON S-2000 flash units (red colored at end of arms) and two FIX LED video and focus lights. All four of these are attached to the camera housing via an assortment of Ultralight connectors, ball joints, and arms. The reason I chose the INON flash units is that they’re capable of true STTL metering with the GH1 via fiber optic cable connections (note the thin wire running from each flash unit to the housing.) The GH1′s flash unit is popped up inside the housing, and fires a preflash just prior to the full power flash. Normally, the preflash is detected through the lens by a metering sensor that instructs the camera to fire the proper amount of full flash for the scene. (all of this takes place so quickly you don’t notice two flashes firing.) However, in this case the camera’s preflash gets detected by the strobes via the fiber optic cable, and the strobes send out a preflash that’s detected and analyzed by the camera. It’s a stronger preflash that fools the camera into sending a “full flash” signal that’s much weaker than normal. (A side benefit to that weak full flash? The camera battery lasts far longer than expected–typically over 500 shots with flash!) However, the INON strobes instantly calculate the difference and send out the perfect amount of full flash between them. The result is a “synced TTL” exposure that’s extremely accurate–and in this case provided by two flash units, extending the range of the flash and the versatility.

Having dual flash units mounted on this system allows for very creative lighting, and each flash can be dialed down or up in power to provide desired lighting ratios. Plus, I could manipulate the Ultralight arms to position the flash units above, to the sides, or below a fish or target in front of me, or move them to the proper angles when shooting vertical compositions–an impossible situation with a flash mounted on the housing or camera. The results speak for themselves in the following photo gallery

Finally, the focus and video lights I chose, both FIX LED units waterproof to several hundred feet, allowed me to switch to the cameras HD movie mode and still have lighting at hand. One FIX light provided 500 lumens, and the other 1000 lumens when dialed to maximum output, lending a perfect 1:2 ratio. However, as I learned when viewing the videos vs the still images of the same subjects, LED lighting doesn’t provide the same color rendering index as the flash units, despite providing a color temperature of 6500k. They’re a bit weak in the red spectrum output, which is really needed underwater, so red objects appear less saturated when photographed or recorded on video when using the LED lights. By the way, the entire lighting system shown above cost approximately $2100, and I’m told the custom underwater housing cost approximately $4,000. Expect a number of housing manufacturers to offer production housings with fiber-optic fittings for under $2,000 in the near future.
Didn’t need the video lights much in this scene, which had enough lighting and action of its own:

Hey, did that White Tip Reef shark just give me the evil eye? Or was he wondering how I’d taste with a seaweed salad? This is a short preview of a 6 minute long full 1080p movie I made in the Coral Sea while doing a documentary for UNESCO World Heritage Photo Project, taken with the Panasonic GH1 in a custom housing.

Canon’s EOS 5D Mark II captures true 1080p HD Video with sound. Image quality and AF controls are minimal in video mode, but depth of field and wide angle views make this a hot feature.

Once DSLRs arrived with Live Preview modes, I knew it was only a matter of time (and several image processing advancements) before the video signal being pumped to the camera monitor would find its way directly to the memory card. I expected the first hybrid models would be from either Canon, Sony, or Panasonic—all DSLR players with a large stable of camcorders. Surprise! Nikon beat them to the punch with its 12.3MP D90 ($899 street) featuring a live view mode that could be used to record 720p video (1280 x720 pixels per frame, at 24fps) with mono sound. Word had barely spread about this camera when Canon trumped it with its more expensive ($2700 street) 21.1MP EOS 5D Mark II featuring a full frame sensor and true 1080p HD video recording (1920 x1080 pixels per frame, at 30fps), plus built-in mono sound and a stereo sound input jack.

You can bet that other video-capable models will be introduced by a variety of manufacturers in 2009 and beyond, just as a Live Preview mode spread from a single Olympus DSLR in 2005 to 80% of the current DSLR models. But the question that many serious still shooters are asking is whether a video mode is a must-have feature in a DSLR, or more of a gimmick designed to appeal to the horde of compact camera owners moving up to a DSLR?

For more commentary on video recording with a DSLR, listen to the October 25, 2008 McNamara Report segment on Inside Digital Photo (slide to the 20min 45sec mark for that segment);

After all, the demand for a DSLR Live Preview mode didn’t come from pros converting over from 35mm film DSLRs, but from a new generation of photographers weaned on compact cameras and their “live view” LCD viewfinders. Those same compact shooters take video recording for granted as well—so why not offer the same function in a DSLR model made just for them?

Ok, I admit there’s a flaw in my logic: The Nikon D90, and more so the EOS 5D Mark II, are really not aimed at compact camera owners looking for their first DSLR. However, the point is that there wasn’t a measurable pent up demand from pros and advanced amateurs for a video recording function in their DSLRs, and now that is being offered, these same serious shooters are trying to figure out if it’s a feature that will help or hinder their ability to make a living with their cameras.

Current state-of-the-art camcorder with high res still capture (including models from Canon, Panasonic, JVC, and Sony) deliver acceptable to fairly decent still image quality, and allow for still image capture that doesn’t even interfere with video and sound recording. When shooting video on most of these models, you simply press the still image capture and a 2-6MP high res still photo is stored on a memory card, while video and sound are recorded to tape or a hard drive. This seamless switch between video and high res still capture modes makes it possible for pro videographers to capture and sell still images of an events to newspapers, magazines, and even wedding clients. In fact, some news organizations are replacing their DSLRs with hybrid camcorders to capture content for multiple platforms.

Unfortunately, switching to the video mode in either the Canon or Nikon DSLRs takes several steps. To shoot video, both cameras must first be set to live view mode—thus reducing the benefits of using the DSLR’s super sharp and bright optical viewfinder, its super-responsive AF system, and most of its advanced image quality and metering controls. Sluggish autofocus can be achieved using contrast detection AF, or after a short black out and delay caused by the mirror swinging back into place for phase detection AF. But once video recording is started, neither camera will adjust focus to follow the action or subject–a staple on most camcorders. Despite the bright and sharp 3-inch LCD monitors found on both cameras, it’s hard to tell if the subject is in focus in the first place, especially in bright light outdoors.

Other video “failings” include fewer image quality controls, reduced battery life due to higher video demands, intensive memory requirements for HD (even short clips take up 100’s of MBs), and generally rotten sound. In fact, the built in microphones on both cameras tend to pick up all sorts of camera and environmental noises, and only the Canon offers an external microphone input jack for recording stereo. Then, unless you have an image stabilized lens or are shooting with a tripod, the video jumps all over the place when you are panning, and freezes for a moment when you take a still photo.

So, is a video mode in a DSLR a useless feature? Not at all! In fact, I’m all for it—and think that cameras such as the Canon EOS 5D Mark II will actually be on the HOT list for pro videographers who want its unique video capability, as well as still shooters who are primarily interested in its awesome full frame and high res still features.

For videographers, the APS-C sized sensor found on the Nikon D90 and full-frame sensor found on the EOS 5D Mark II make it possible to shoot HD movies using a wide variety of affordable wide and ultra-wide angle lenses. (Want a 14mm equivalent field of view on an HD camcorder? HA! It will cost you a fortune.) Those larger sensors also dramatically improve depth-of-field control so that backgrounds can be blurred out with unparalleled Bokeh. (The relatively small 1/3-inch to 1/5-inch sensors found in typical camcorders require lens focal lengths that deliver too much depth of field and make it impossible to blur out a background, even at widest apertures.) For more information regarding the still shooting and video capabilities of the Canon EOS 5d Mark II, check out the incredibly well-written Canon white paper on the EOS 5D Mark II.

Having a video alternative may allow traditional still photographers to capture video footage that would be impossible otherwise. For example, underwater photographers could switch to video mode at a moments notice to capture the fluid motion of the rare Pacific Mermaid, while mountain climbers could record the mating call and ritual dance of the Himalayan Abominable Snowman. In both cases, it’s impossible to carry separate still and video cameras.

Before those unique video segments ever appear in a National Geographic HD special, the video from cameras such as the D90 or EOS 5D Mark II will flood internet entertainment sites dedicated to capturing the latest celebrity outing or “Girls Gone Wild” moment. For example, one of the best nightlife and fashion photographers I know, Shane O’Neal, covers a number of top clubs in Las Vegas, including the Playboy Club and Club Moon at the Palms Hotel and Casino. (www.shaneonealphotography.com). With an EOS 5D Mark II in hand, he is able to switch to the video mode and capture dancers, celebrities, and “wild” patrons doing what they typically do at these clubs after a few drinks, and post short video clips to the club’s web site along with still photos. In the past, capturing video required a separate videographer on hand (at an extra expense). But now he can do both, and no one knows he’s actually recording video with sound. The result? Some unique, and wild video that helps increase traffic, and may generate sales of hot video footage.

What’s next? I expect the next generation of dual-mode DSLRs to improve on video ease-of-use, sound recording, and AF speed and tracking performance. Then I expect to see some hybrid accessories, such as a dedicated flash unit with a built-in stereo zooming microphone, an external 5-inch LCD monitor, external Firewire-connected high-capacity storage drives dedicated to video recording, and additional powerpacks to handle the video power drain. But don’t expect the camcorder crowd to go away. In fact, 12MP camcorders are on their way.
