I've run into a problem with my Zenza Bronica Etrs film back recently, when I remove the dark slide from it and go to take a picture it locks like the slide is still in it. It has something to do with the little mechanism that the little tab of the dark slide presses on, i've tried working on it to get it back to normal but nothing has really worked. A little ball bearing came out too but im not sure if that's part of the problem and I cant find a spot for it. Thank you for your help.
