Bought a c330 with 80mm a few months back. Ran 5 rolls through it, no problems. Then one fine day, I loaded a new roll, shot 2 frames consecutively, upon trying to advance the film, the lever just jammed up on me. It did not want to turn over.
I tried switching to 'multiple', didn't work. Tried to work the shutter a few times, didn't work. After 15 mins of cocking the lens and firing off the shutter and other stuff, the lever finally came loose---worked like a charm after that.
However, I was shooting a personal documentary project. I do not wish for that moment of helplessness to happen again.
Any ideas on what's the problem? Ways of rectifying it?
