To all other Widelux users out there: have you ever experienced overlapping frames, and how often? My unit seems to do that very often, or at least too often for my taste. It doesn't surprise me too much, seen the transport mechanism: it's very easy for the film to slip over the sprocket as nothing pushes it firmly against it. But it could be something else (some friction, some gear...). Useless to say there is no longer any repairman I can count on in Italy anymore. I wonder if using 36 frames films may be the issue. Perhaps I should limit to 20-24 films. Any opinions?
