MelissaP, I also own a T21 (just for about a month - I'm a total photography newbie) and it rolled off my table today (about 2.5 feet). My camera was snug in it's camera bag, but of course I'm freaking out, trying to figure out if any damage has been caused! I've done test shots and looked at all the other suggestions from everyone here. Everything seems to be okay. The only thing I notice different is that the manual zoom is a little "grabby" instead of smooth like it was before. Did you have any issues with that? I wonder if I should take it to a camera shop just for a quick once over?
