Yes, I did have similar problems. Fortunately we had several S2s so I would just swap out to a working one and send the jammed one to the repair shop. I believe at the time we would send them to Strauss Photo-Technical in Washington, DC. for repair. Can't remember what the exact problem was as this all happened over 30 years ago. I just remember they were Bronica S2's, always took two complete cameras with me on wedding shoots and never trusted another Bronica product after that. Sorry, just my personal experience. I'm sure many Bronica owners are very pleased with their cameras.
