I went to a small camera show a few weeks ago and somehow came home with a Zeiss Super Ikonta BX (533/16).
It's a beautiful machine and the meter still works, but the film advance mechanism has some issues.
Can someone please tell me the purpose of the small button to the left of the film advance knob? It doesn't seem to do anything on my camera. It would help if someone explained the exact sequence of actions used for advancing a new roll, winding between frames, and resetting.
I have an issue with the frame counter not advancing and the film not smoothly advancing. I disassembled the film advance knob and frame counter ring and it looks like someone incorrectly assembled the mechanism although I can't tell exactly how it's supposed to fit together. Does anyone have an exploded view or detailed instructions on how the assembly fit together. Thanks.
