I ran my first roll of film through my Zenza Bronica GS-1 today. I'm still hunting for a standard lens but have managed to find a 50mm and a 150mm. I'm also hunting for an AE finder. But I decided to give it a whirl anyway with the waist level finder. I removed the speed grip since it just doesn't look right with the WLF. Everything seemed to be working fine except the crank is acting strange. Sometimes it would work normal; which means after taking a shot you just give it one full rotation and it stops and you are ready to go. But then other times it would just keep turning and turning. The frame counter window showed that the film was only being advanced one frame, but for some reason the crank just kept going around and around. It felt exactly like it does when there is no film in the camera and you don't have it on "multiple exposure". I was not using the MLU function or the multiple exposure function... just shooting in the normal mode. But if I kept cranking it, or stopped a bit and then tried it again, eventually it would stop. Any ideas as to what is going on?
