I have a Canon Rebel and this past weekend i was taking some pictures of my cousin and her new baby and it was acting right at first but then it got to where it didn't want to focus. It kept acting like it was having problems. I tried a differently lens and it still was acting crazy. Has anyone ever experienced this? I am going to be near the best buy that I bought it from this week and I am trying to decide weather or not to take it and send it off for repairs. Could it be something I am doing wrong or the camera needing to be looked at? I hate to have to send it off b/c it will probably take a few weeks to get it looked and and fixed. I don't want to be without my camera that long!!!
