Hi all, Just joined the list and hope to learn more from you all. Got my Rolleiflex 3.5 today and very excited. My first TLR. =) I put an exposed roll of film to the camera to 'test' it and to make sure I know how to use it before I put a real roll of film. Rookie needs to practice, I guess. I did the shutter testing without loading film and the shutter speed seem pretty accurate. So I load an exposed film according to the manual. I was able to advance the film, release the shutter, and repeat the process until suddenly I can't advance it anymore. It some time stop at 2nd frame, 1 frame, and the most I am able to advance is till 8 frame. I can't turn the handle both ways. I had to remove the film, then the shutter count jump back to 0 and everything works fine. My question is, is there a problem with my film advancing mechanism? Or is the film that is causing the problem? Thanks for your help in advance. How do I identify where it went wrong? Sincerely, Lee
