I went out for a little photoshoot this evening and used my cannon 17-85 IS lens on my XTI, we were shooting for a good hour or so. I had it set on a 10 sec. timer with a 4 sec shutter speed, after the four seconds I heard the shutter close but the screen remained black and the green light above the "ON" letters stayed on, at first I thought maybe I had lengthened the shutter speed but after about 45 seconds it stayed the same way. So I starting pushing buttons and nothing happened then I turned it off still nothing the green light was still on I had to take out the battery. I turned the camera back on and everything was fine until I tried to take another picture and then the same thing happened. I tried taking off the lens and putting it back on then the memory card and also tried switching to full auto mode using flash but the same thing happened. When I got home I tried again and it only took one picture on the second try it froze up again. I switched to my 50mm and now everything is fine. Also when it froze as I took the picture you could see the picture through the viewfinder shift a little bit.


Has anyone had this problem??? Sorry for the long write up, I'm trying to be as detailed as possible.
