Canon’s 21.1-Mpixel EOS 5D Mk II dSLR with 1080p HD Video: Burn (those bits) Baby, Burn

September 17, 2008

Last month, Nikon introduced the 12.3-Mpixel D90, the world’s first dSLR with video.

Today Canon fired back by introducing the EOS 5D Mk II dSLR, a full-frame, 21.1-Mpixel dSLR that can also record 1080p HD video. It was a much anticipated introduction. There are several interesting innovations in the new Canon dSLR. Central to the camera is the 21.1-Mpixel sensor, which employs microlenses that are bigger then the CMOS receptor sites to gather as much light as possible. As a result, the EOD 5D Mk II dSLR sports an ISO sensitivity range of 50 to 25,600(!!!). It remains to be seen what the noise looks like at the high ISO settings.

To handle that many pixels and get them into Flash memory while shooting at full resolution at the camera’s maximum rated 3.9 frames/sec, Canon developed a new image-processing chip called the DIGIC 4. Canon’s existing DIGIC III processor was already recognized as a very fast image processor. DIGIC 4 is reported to be 30% faster. Reportedly, the 1080p, 30-frames/sec video encoding is performed by a separate H.264 chip. Canon also introduced five other cameras today, all based on the DIGIC 4 processor: the Powershot G10, a 15-Mpixel compact camera; the 10-Mpixel PowerShot SX1 IS and PowerShot SX10 IS cameras; the 15-Mpixel Digital IXUS 980 IS compact camera; and the 10-Mpixel Digital IXUS 870 IS compact camera.

Canon had previously introduced the Digi 4 processor with its 15-Mpixel EOS 50D dSLR. According to Canon, the “DIGIC 4 Image Processor offers finer details and even more natural color reproduction, compared with the previous DIGIC III Image Processor. Since Canon’s DIGIC 4 chips use advanced signal processing technologies, they provide even faster operations, including write times to UDMA cards. [The DIGIC 4 processor] also enables Face Detection Live mode to detect and focus up to 35 face(s) to capture the best possible shot. Further, DIGIC 4 offers the improved Auto Lighting Optimizer that corrects brightness and contrast automatically, and Peripheral Illumination Correction for up to 40 EF lenses.” The DIGIC 4 processor also handles the 14-bit data coming from the image sensor.

DIGIC 4 is an ASIC developed by Canon engineers. It incorporates proprietary image-processing algorithms developed by Canon. This ASIC is a good example of how systems companies can differentiate their products with processing horsepower and proprietary algorithms. However, it’s clear from these cameras that processing differentiation alone isn’t nearly enough in the camera market. Sensors, optics, user interfaces, and other features (like video) are equally important.

And yes, yes, yes, I want one. List price for the body is $3499 $2699.

[UPDATE] By a strange coincidence, DSP guru and BDTI president Jeff Bier published an opinion piece in his Inside DSP newsletter this same day covering the philisophy behind Canon’s series of DIGIC image processors (although he doesn’t explicitly discuss Canon). The article, titled Proprietary Algorithms Key for Embedded Processor Vendor, discusses product differentiation through algorithm optimization. Bier wrote:

Processor prices are dropping, while processor performance is increasing. Every year you get a lot more bang for the buck, and it’s getting easier and cheaper to implement a wide range of embedded applications on lots of different processors. But chip vendors still need to differentiate their offerings.  One way to do this is for them to offer proprietary algorithms that can only (or most efficiently) be used in conjunction with the vendor’s particular processor…

Steve Leibson commented:

G: Minolta (now Sony), Pentax, and Olympus are three vendors who have implemented image stabilization (IS) in their dSLR bodies. Contax even did it with a film camera, a really neat trick. The trick is conceptually simple. Mount the image sensor on an XY table and then slide the table around to compensate for camera movement. It works. The reason Canon didn't do this was because it had several camera bodies in the EOS series back in the film days so adding IS to the lenses automatically added the feature no matter which body you owned. If you were starting now from scratch, it might well make more sense to put the stabilization in the body. Want to read more? Try www.bobatkins.com/photography/digital/image_stabilization.html

Regarding the comment about IS in the body. I am not sure if this is even possible. The lens relative to the body of the camera in an SLR is much heavier. It might be impossible to stabilize the body without stabilizing the lens. Just my two cents, I'm no expert though.

Dave, I completely understand your objection. You feel that the addition of video positions the 5D Mark II down with the "toy" compact cameras. However, the addition of a microphone, an A/D, and a mike input jack probably raises the factory cost on this $2700 camera body by two bucks. What does Canon get from adding video to this high-end, full-frame dSLR? For one thing, it gets thousands of salivating professional wedding photographers who are already lusting for this camera because they know they'll instantly be able to make more money from their gigs. You can get 10 compact cameras for the price of a 5D Mark II camera body. This camera doesn't compete or even mingle with the toy cameras. It's entered a new niche: a high-resolution still/video image-capturing engine with interchangeable lenses from a top-of-the-line optics manufacturer.

Dave commented:

I have a problem with the "more, more, more" attitude. I'll probably still buy a 5D mark ii down the road, but the video feature is really a turn off for me. It's a still camera and that's what I expect it to be. I'm an Electrical Engineer by trait and certainly understand the fact that once you add live-view it's a quick step to the video feature. So I don't dislike the video feature because I think it added any real manufacturing costs, or R+D for that matter. I was basically ok with the idea until I read it had an internal microphone. I just don't want a microphone in my still camera. I hope canon does not add this to all of their top level cameras. I hate when products become "bloated" and start getting into areas that they shouldn't be in. The video idea seems like a great addition to a point and shoot, but not for a professional grade still camera.

Gordon McGregor, thanks for stopping by and leaving a comment. I've been surprised at the negative comments I've seen about the 5D Mark II's video abilities. Many shooters (or perhaps it's just a few really noisy ones) seem to think that the video abilities somehow diminish this 21-Mpixel camera. Say what? You get more, more, more. Be happy, don't worry. That's what I say to them.

Gordon McGregor commented:

I've been shooting with a 1DII for years and am really excited to pick up a 5DII. The video feature is really interesting to me, as a still photographer who dabbles a bit with putting together sequences at 8.5fps. There are a lot of photo journalists and newspapers that are moving towards integrating more video into their work, it seems like a natural progression, for something that is still in the form factor of a still camera, to have some video capabilities. From this video, at blog vincentlaforet com ( I can't post the link in this comment box) It gives Canon's high end gear a run for its money for low light performance. Interesting times.

I almost plunk down 8K for 1Ds Mark III last week. I am glad that waiting two more months I will get as good as a camera for almost a third less. Thanks Canon! I'll spend that dough I save toward the 85mm 1.2L lens. Please have holiday rebate program and I'll get another wide angle lens with it.

Tuan commented:

Each technology costs research, development, design and test. If they do the IS in camera for you, are you willing to pay the additional cost ? Also, you have to look at Canon''s point of view, they lot of lenses that have IS built in. Now you expect them to do in camera IS, doesn''t that sound to stupid to them ? Think...a little harder. and just don''t take things for granted. You''re lucky you were born this time. Just imagine what your life will be, or any idea what the camera is if you were born let say 1000 yrs ago.

RAWShooter: Many like-minded people have bemoaned the addition of video to a high-end dSLR like the 5D. They think that somehow, this feature has boosted the cost of the camera and they don't want to pay for a feature that they don't want to use. There are two issues here in my mind. The first is use. I can easily envision some types of pro shooters, particularly those who shoot weddings and X sports like skateboarding and BMX, that will be thrilled to use the 5D Mark II's video while shooting stills. The second issue is cost. Once you've put live video in place as a focusing aid, you get video by doing not much more than recording the live-view image. Again, not everyone wanted live view in the first place, but some people do. For example, as a macro shooter, I'd like to have live view because I can't always get my eye to the viewfinder in a macro shot. Ditto some car shooters who have posted comments on the Strobist Flickr group (highly recommended). As for your other suggestion, I agree that having image stabilization (IS) in the camera certainly reduces the overall cost of IS. On the other hand, I've seen Canon improve in-lens IS several times and I get the benefit of those improvements each time I buy a suitably equipped lens, so I can't say Canon's approach is clearly wrong. Just my opinion.

RAWShooter commented:

This is strange. I personally think the 5D camera (with it's full frame sensor) is targeted more for the professional and pro-sumer crowd. Not the casual shooters/tourists that want to shoot photos and videos in the same device. Instead of video, I would love to see Canon move the I.S. (Image Stabilization) technology into the camera, instead of putting it in the lens. It gets pretty expensive fast buying multiple IS lenses (L-series). If the IS is built-in the camera, then no matter what lens you use, you get this capability. My daughter's little Canon point-n-shoot camera has this I.S. feature built-in... while my big hunking SLR does not. I predict the next feature Nikon and Canon will add to these cameras will be MP3 players and a headphone output jack. So you can be listening to tunes while shooting photos. :) .... and yes, I want one of these new 5Ds!

Must be an ARM7 processor inside that DIGIC 4.
