I've recently acquired a Bronica ETRSi and I'm having issues with it (1) Winding on the film and (2) Firing the shutter. I'm wondering if anyone might have any suggestions.
There are 2 levers on the side that control double exposure and mirror lockup, to which I have tried the 4 permutations in order to try getting the shutter to fire etc.
I noted that the manual spool winder on the film does indeed spin when I am spinning the film/shutter winder, proving that the double exposure switch does move the geared wheel into the correct positions.
FYI - I checked that everything was in the right configuration during the test. Film loaded, lens attached, dark slide removed, shutter button lock disengaged etc
