The ledge which I have to press before rotating the aperture dial suddenly lose tension. This means when I press it, it doesn't go back to it's original position (which means the dial is free at all times). Any advise on what can I check? I removed the dial and saw a metal thingie there but I don't see any spring etc which makes it 'bounce' back to position.
I do have a similar problem indeed. I would be happy if you could tell me if I have to open up the whole camera and try to fix it, inside. I can't see the trick to make the dial coincide with the 22 aperture: as soon as I go up to 8 or 11, the inner mechanism stops and the aperture corresponds to an 8; meanwhile the aperture ring can be rotated but is loose. There is no tension anymore.
