Hello I wonder if I can pick your brains over an unusual issue for me. Yesterday I developed two rolls of FP4 shot with my Minolta XD5. Both rolls had 3 to 4 completely blank frames. No exposure whatsoever. The rolls were shot on different days. The camera is in excellent condition and I have shot several rolls on it before without a problem. Afterwards, I have done about 100 dummy shots with no film in the camera at different settings. Each time the mirror, shutter and aperture works just fine. No misfire. Metering seems accurate. My thoughts on this is that it may be a film tension issue, causing the film to bulge and block the blades of the shutter. Perhaps an issue with the pressure plate? Before I start tinkering with it, do you have any ideas or suggestions?
