OK, so I was sitting down and talking while loading film. Last time I do that. Fumbled my OM2N while the back was open and it dropped onto the carpet from about knee level. It wasn't a long way to fall but it seems to have bent the door somewhere, now it doesn't close properly without a slight push upwards. Am I OK to gently bend it the other way or is that going to wreck it further? This is my main camera, the one I bought from John @ camtech, so it'd be a real shame if I break it further. Thoughts?
