Hello sbjornda,

I have two other 120 camera; a Rolleiflex TLR that I use frequently, and a Mamiya 645 that I use less so. I don't see this problem on those cameras. I don't think it's a problem with the film, as the mark in question appears in the same place on the 6x7 neg(9mm from the right hand side of the neg) on every frame. To me, that indicative of something in camera, not a film defect.
