Hi I am a new rollei user having recently purchased a lightly-used 2.8FX.... Needless to say I fired off a couple of rolls pretty quickly. 2 of them were fine but to my horror on one of them there was a pair of partially overlapping frames (about 1cm) - presumably the film had not been sufficiently advanced. Its quite possible of course we have a case of user error - that I did not bring the crank back fully to the stop position. But I would have thought that if I had done so I would not have been able to release the shutter? On checking it out later with a dud-film I found that it does appear to be possible to get a shutter release without a 'full crank'. Any thoughts on whether I may have a problem or is it simply a case of 'rubbish-in; rubbish-out'? best rgds Mike
