Since I own and use both Canon and Nikon cameras, I can honestly say that I have no allegiance to either of the competing brands. I use the Canon EOS 1D Mark III for reporting because of its 10 frames per second, and I use the Nikon D800 for portrait and landscape photography because of its 36 megapixels, insane detail, and wide dynamic range. The Canon EOS 7D is a good equipment for the amateur market, but it is honed solely for the purpose of reporting and makes no claim whatsoever about the artistic quality of the picture it produces. At first look, the working ISO appears to be quite high; nevertheless, this is only appropriate for documentary work, as ISO 3200 completely destroys the image (dynamic range and detail) Imagine that you are shooting a report in low light conditions at an ISO of about 3200 at 8 frames per second, respectively. You repeatedly the exposure will change, and with these shooting parameters in post-processing, you will not be able to stretch the shadows in any way, as a high ISO value simply nullifies the dynamic range. Although the sample isn't exactly polished, it's not too difficult to grasp even for novice photographers. In my personal view, it is a solid reportage camera that is on an entirely amateur level.
