I just wasted a roll of film. It turns out that as soon as you put film in the
magazine the friction of the film makes the locking mechanism in the film magazine
immediately snap into place. Hence, the slight movement of the cog has no influence
here. Its not able to move the film.
I also tried to touch the film plane during exposure and in all but one frame the film
was perfectly flat. However, in the one frame the film moved slightly under my finge
until it stopped against the pressure plated. Granted, we are talking mm's here but we
are anyway talking about bulging film at the pressure plate. I cannot for the life of
me figure out what causes this...
