I have been having trouble the last few times I have used my Canon 50D. 1. Several times I have gone to take a picture, you would here the click the lens taking the picture but it would never unclick. like it started to take the picture and then it never finished. 2. When the shutter is released the camera is making a very strange sound it is hard to describe but it isn't the normal operating sound. When the release happens there is a high pitched noise that goes off. like i said it is hard to describe but it almost sounds like a turkey call. any ideas on what could be wrong? The camera hasn't been dropped. The body caps and lens caps are always on when the camera isn't being used. The camera is less than a year old.
