My Canon Rebel Xt just recently stopped taking pictures in auto focus. It will adjust a couple times then nothing. it works in manual mode. I took it to best buy and tried another lens on it to see if that was the problem and it didn't work with that one either. I read on the Canon website to clean the lens contact thingys and I did. but still no luck. I'm just wondering if anyone has some suggestions or anything....I just want to know if there's something I can do other than buying a new camera.
