I have recently gotten this camera and it seemed to work just fine. The last time I went to use it the meter was all strange. It meters but does things like f2.8 at 4 seconds in low light. Bounce the camera about a bit and it changes. Even changing the shutter speed has little or no effect. I've tried new batteries and everything I can think of. Someone had at one time mentioned that if a non-ai lens was mounted something could be bent and that might be the source of the problem. The fellow I got if from said he used non-ai lenses on it regularly. I'm guessing it could also be dust or some such. Does anyone have anything they can tell me to check in the hopes of a quick fix?
