Canon EOS 5D II: Early Observations on Image Quality
I posted earlier today about increasing availability of the Canon EOS 5D II at places like B&H, so I thought it might be useful to begin posting on some of my experiences with the camera during the couple of weeks (and perhaps a thousand frames) that I’ve had it. Here is a copy of something I posted elsewhere earlier this week, in response to a post concerning image quality from this camera:
I’ve shot with cropped sensor bodies extensively in the past. I have shot with a full-frame 5D for the past two years. I recently began shooting with a 5DII and have done a thousand or so frames with it.
I cannot see image quality problems in my images, even in those that stress the ability of the camera in ways that should produce them if they are there: shooting wide dynamic range scenes, using high ISOs (up to 1600), inspecting at large on-screen magnifications, and making careful prints.
My photos have very low noise all the way through the shadows to pure black, even in some photographs where I’ve pushed the shadows either during RAW conversion and/or via the shadow/highlight tool in post. I’m seeing very highly detailed images with smooth tonal transitions. As far as I’ve seen the 5D II has a rather substantial dynamic range – as reported in a number of tests – and it is at least as great as that of the 5D.
Let me repost a couple of 100% magnification crops that I posted elsewhere from the 5DII.
The first was shot at ISO 100 at, IIRC, f/16 using a 35mm prime with the camera on tripod. The crop is a 100% magnification section from the very far lower right corner of the shot. The dark areas were pushed slightly, too, so if there were noise anywhere it would certainly appear here – but I don’t see it even at this resolution, which would be equivalent to a print width of five or six FEET wide. Seems like pretty good resolution to me! (It also speaks well for the EF 35mm f/2 lens.)
The second example is pretty much a noise “torture test” – it is a very dark section of a much larger image. (Again a 100% crop). It was shot using a 100-400mm zoom handheld at ISO 400 in cloudy conditions. There is some noise in the shot, but that is entirely normal – and this noise would be completely invisible even in a very large print. (The pattern on the lighter fabric near the left side of the frame is that of the fabric itself.)
My observations from 100% on-screen pixel peeping are confirmed by the more important test of printing.

Cycling Week at the Blog
The Amgen Tour of California comes to my part of the world every February, and I take advantage of the opportunity to shoot a different sort of subject than those more typically found here. So the next week or so may be a sort of “cycling week” at my blog as I post photographs of the first few stages.
Yesterday I attended the first event, the prologue time trial stage in Sacramento, California. While in some ways a time trial can be the least exciting type of cycling race given that it is purely one rider at a time against the clock, on the other hand this type of event provides tremendous opportunities to photograph the riders – and this is largely what I concentrated on yesterday. Before the race I photographed groups of riders doing their pre-race circuits of the course and then I shot a number of them as they warmed up by the team vans. Later, during the race, I picked a few good spots and photographed riders as they came into view one by one.
Today’s stage runs from Davis to Santa Rosa. The original plan was to be at the starting line in Davis and then head on over to Santa Rosa, but the weather today is just plain awful. We’re foregoing the start in Davis but we’ll try to be at the finish line in Santa Rosa when the group comes in later this afternoon.
A Bunch of Saturday Links
This past week I came across a number of interesting links. I didn’t have time to post then, but now that it is the weekend and I have a bit of time, here they are:
- John Paul Caponegro has been posting frequent updates about a photographic expedition to Antarctica at the John Paul Caponigro Blog.
- Speaking of Antarctica, the Boston Globe has published a stunning series of photographs from Antarctica, made by a variety of photographers all over the continent.
- Over at his blog Jim M Goldstein has reported on his hard drive disaster and his successful efforts to recover. He also shares some interesting and useful ideas about backup strategies.
- Yosemite photographer – and author of a highly regarded book on photographing in Yosemite – has started a blog: Michael Frye Photography Blog. He has a lot of good information to share about photographing the Valley, and he has already published useful information about photographing the iconic Horsetail Fall in the next month or so.
- Andy Frazer has offered another in his ongoing series of commentaries on night photographers, this time with words about and links to Aaron Hobson.
All good stuff!
