Hi again Jazz
You recieved the Zenzei Without a darkslide ?
You shot a film ? It should be ok unless you opened the back midroll.
With the darkslide in place your shutter wont/shouldn't fire. The only use you have for the darkslide is when removing the back from the camera. that cannot be done without it in place.
Beware of the multiexposure lever. you can activate it when dryfiring the shutter but remember to deactivate it before real use (unless you want to multi expose ofcource)
BTW con gratulations, the Bronica is a great camera (Ive got a SQ-Ai)
Ill be back if I come up with some hints
Regards Søren
