I just bought a Canon AE-1 - my first analog camera, yay - and I'am shooting my first roll of film. I'm in the middle of a roll right now and I've noticed something that's worrying me. When I wind the film on, the rewind knob is meant to turn as well, right? So, what I've noticed is that, sometimes, the knob don't complete its turn. Instead of the normal +-180º turn, it only goes halfway. I've already checked if the rewind button was pressed and tried turning the knob clockwise to give some tension to the film, but it seems to be random. Anyway, the exposures counter keeps advancing normally since the beginning of the roll. Should I be worried about the photos being overlap?
