Sometimes i got strange lines on my 120 negative (see atached file), the negatife its self seems ok.
I recently changed the lightseals (foam and u shaped plastic) on both my A12 and A16 film backs.
I bought the camera a few months ago and it is +/- 20 jears old.
Can anyone tel me what the problem is ?
The best thing i can guess that there is something with the mirror..
