I bought an old Canon AE-1 35mm SLR that is in excellent condition- not a ding or scratch on it. I used it for one roll of film (Have not developed it yet) and when I went to put in a new film- it would not let me use the advance film trigger. I read the manual over and over, and I do not remember it being this difficult to merely change the films when we put in our first- so I am guessing something is wrong with this camera. It simply will not advance the film- the trigger moves half way, but not far enough to advance the film the slightest bit at all. Therefore- I cannot load the film. It is time to call it quits with this old camera already?
