I am wondering if anyone can help me. I have a Canon 50D and have never had any trouble with it. Just recently (the day before we left South Africa after a four week holiday) it decided to stop taking photos. I am so thankful that it was at the end of the holiday and not at the beginning. When I turned it on, everything showed on the top screen up but when I tried to take the photo - the camera beeped as though it has focused, but the shutter button wouldn't take the photo, no matter how hard I pressed. I tried taking the battery out and reinserting and tried it with different lenses, with no success. I tried it a few days after coming home and it will now take photos, but I have to have my finger in the right spot on the shutter button and I have to press hard for it to take photos. I now have it set to multiple shots and whilst I have to press hard to take the first photo, but the subsequent multi photos are taken rapidly. I first thought that the shutter may have gone, but now I am not sure. It is a real mystery to me.
