Canon 7D
Well, I finally took the plunge. I've just recently purchased a lightly used Canon 7D.
Lots can be found on the internet about the 7D's specs, particularly in regard to bird photography. A while back I had decided on a Canon DSLR system, but it took me a while to decide which body to purchase. I narrowed things down to a used 40D, a new 60D, or a used 7D.
I had ruled out a used 50D because reviews from birders seem to find little upgrade from 40D, and they are going for $200+ more than used 40Ds. I also ruled out a new 7D because, with the camera already being over 18 months old, it will be due for a successor sometime in the next 18 months. I thought the 'lightly used' option would be the way to go if I wanted to upgrade to the eventual successor, because I won't end up losing as much in depreciation over a short period of time.
