| p.1 #7 · 7D vs. 1D3 for wildlife work (input needed) |
I'm currently using a 1D Mark IV and 7D primarily for wildlife shooting, and I previously used a 1D Mark III.
While I loved my 1D Mark III and got lots of excellent shots with it, I wouldn't sell the 7D short. If I was shooting in situations that were not focal length-limited, I'd probably say that the 1D Mark III has more going for it, but, in focal length-limited situations, the 7D has some significant advantages. If you have to crop a 1D Mark III image down to the same field of view as that of 7D image, you will be down to fewer than 7 MP on the cropped 1D Mark III image. Even if, on a per pixel level, the 1D Mark III pixels are of a higher quality, if you have to up-rez to make a decent-sized print, that advantage is lost.
I know that there are some who really enjoy bashing the 7D, but I think that the bashing comes largely from people who fail to accept the fact that, with a high pixel density sensor, especially if you are going to crop, you need to keep your shutter speeds at significantly higher levels than you would with other cameras and from people who insist on comparing noise in a totally invalid manner by looking at images at 100%, instead of looking at them at the image level.
I'm currently finishing up a 5 month long project where I've been visiting an eagle nest virtually every day and documenting the nesting progress. While the single chick was in the nest and the action was all around the nest, I shot from a tripod with my 1D Mark IV and 500/4. Once the chick fledged from the nest, I have continued to follow it out of the nest for the last 6 weeks. When following it through the marsh, brush, etc., a more mobile camera/lens combination has been an asset. So, I switched to using the 7D and my 400 DO (which is another piece of equipment that those with "internet wisdom" love to bash). The 7D/400 DO combination has not let me down in any way. Its AF has been completely up to the challenge when I've been shooting fast moving action with busy backgrounds, and, if I didn't know which images were taken with which camera and lens, I wouldn't be able to guess because, in actual prints, I don't see any visible difference whatever in the image quality of what I got from the 1D Mark IV/500 combination and what I am getting from the 7D/400 DO combination. And, since many of the images have required significant cropping, I know that I could not have gotten the same images with a 10 MP 1D Mark III.
If you are interested in seeing some of the nest pictures from the 7D, I can provide a link to them on my site.
