I just got my first Leica M6 and am (of course) trying everything out extensively. Unfortunately, I am facing the known problem with the frame counter that is not resetting to zero when opening the bottom of the camera. The camera goes back to the seller next weekend to get this fixed.
In order to discover everything else that might need some attention, I have two silly questions:
1) How do I notice that the film is fully exposed? Even when reaching the max number of frames on the film roll, I can still wind the rapid-advance lever and also press the shutter release button like for normal exposures. I did this five six times before finally rewinding the film.
2) I noticed that it only takes a few winds of the rewind lever to fully rewind the film. Is this normal or is it a sign that the rewind mechanism is not working properly? Or might the prior owner possibly have changed the wind meachanism to two or three stroke? And how could I identify that?
