I was taking pictures at my nieces 16th birthday party Saturday night and while shooting, I would get a "busy" message on my screen and I couldn't take any photo's for about 6 - 10 seconds. There was indoor fluorescent lighting and the camera was set to Auto and Portrait mode. I was using the 18-55 mm lens. Oh, and the battery was fully charged.
I took pictures of my niece and her friends in front of a backdrop (set up like prom pictures). I would take 2 to 3 pictures of each person so they could pick the pose they like best but between snaps, I would get the "busy" message on my screen and have to wait several seconds before I could take another picture. Very frustrating. I'm just learning to use my T2i and still don't know a lot about the camera. I was just hoping it was something I had done and not my T2i. It's less than a month old. =/ Thanks for your help!
