Nina, Julie,
I shot the 7D at this year's Rottie National so I know what it can do. To get moving shots like this:





I need to shoot longer bursts and get my timing right. "Perfect" moving shots are my candid bread & butter and higher fps usually means a better chance of capturing that exact moment when the dog is fully-extended on one side and fully-contracted on the other.

Having said that, that first image was taken with my 40D and the second with the 7D. Clearly, the second was harder because it was indoors, high ISO, slower shutter speed, etc. but when I review my action shots from the 40D, I'm not disappointed. Nina, thanks for the feedback and I'm going to rent a 50D for some shows coming up in Jan. and, if I like it, I'll probably buy 2.
