The first photo was taken soon after daylight in a meadow along Winslow Hill Road. This photo could have been taken with any of the DSLR cameras that I have used since 2003, although the Canon 10D would have shown a substantial amount of noise at ISO 640 under these lighting conditions. Had I been using it, I would have used a lower ISO with a lower shutter speed in hopes of getting a better quality photograph, but it was possible have greater margin of safety against problems from motion-blur, with the MK III by using the higher ISO settings.
|6x6 Bull at 6:08 a.m.: Canon 5D MK III- 500mm F4.0 1/200 sec. F4 ISO 64|
|6x6 Bull at 6:20 a.m.: Canon 5D MK III- 500mm F4.0 1/500 sec. F4 ISO 640|
|6x6 Bull at 9:13 p.m. : Canon 5D MK III- 500mm F4.0 1/30 sec. F4 ISO 12,800|
The last photograph does show quite a bit of digital noise and is not something that one would submit for publication or make a large print to hang on the wall from, unless it was of an exceptional animal. It is a usable image and as such is a drastic improvement over any camera that I have used to date. I do not claim to have a wide range of experience as financial considerations keep me from owning a wide variety of brands and I have not bought the top end Canon cameras either, but used the 10D, 30D, etc. class camera, until the 7D came along in 2009. This is my first foray into using a full-frame sensor. Everyone I have talked to that owns a full-frame camera has told me that they prefer them to the crop-sensors and my experience so far seems to bear this out.
I am less than thrilled with the full-frame for video under certain circumstances; however. It is definitely better than the Rebel T3i or the 7D If one can get close enough, but that is a problem with wildlife in many cases. Canon did not see fit to put a 3x Crop mode in the 5D MK III, as they did in the T3i, which really cripples it for long-range wildlife filming.
