I'm using a Nikon D3100..however, I'm planning to upgrade to a Nikon D7100 when I can. I think the D7100 is better suited for wildlife photography, and is sealed (weather proofed) which is a big plus if you get caught out in the rain, and has a built in auto focusing motor integral to the camera which allows use of more lenses that don't have an auto focusing motor built into the lens. That being said, the D3100 is a good quality entry level camera. I just wish I had an auto focusing telephoto, (they do make them) I use a 70-300 lens but it is manual focus on this camera..worked good on my film camera a Nikon F5..and my eyes don't always "see" the same as the camera. Hopefully down the road I can get what I really need..quality glass!
