Canon 5D Mk II, 1D Mk III, and 70D ... L glass, USM glass, and a single piece of Sigma glass . . . the better question to define is - what is your budget, and how expandinble do you want your set up to be? For my line of shooting, it takes a bit of gear to range what I use - bird photography uses a 500 F4 IS L lens, while snake photography uses a 100mm F2.8 USM macro lens, and habitat shots use a 17-40mm F4 or 18-35 f1.8 . . . If you want a catch all camera that can do general purpose photography for your snakes, and still be considered a good camera - look at the Fuji point and shoots. Their XRF cameras are impressive: With a budget less than 400 USD right now - I'd look at a Canon EOS M kit with flash from bhphoto, or the Fuji X10 if I wanted to stay closer to the 300 point. If I needed to spend 200 or less, there is a nice Fuji in that range too. Have closer to 600 to spend? Then consider the Fuji x100 used on ebay or FM Forums. 750+ you can start considering a DSLR and get a cheap body and nice lens that works for your needs .
