I had a Canon Rebel t4i, until it was recently stolen from an Enterprise rental car (long story).
It's not a super professional camera, but it does everything you need (I think Canon's up to a t6 now). I got a lot of photos out of it that I'm super proud of.
Like someone said above, the lens is important. Only downfall to me was it only shot about 3 frames per second, so sequences didn't really happen.
I've never actually used it, but I've heard good things about
https://www.keh.com/ It's a site for buying and selling used cameras. Might be able to find something fairly nice for a lot less.
Anyone used the 7dM2 yet?
