Hi, I'm pulling my hair out (if I had any) over this problem. I have just invested in three Mamiya 6x9 film backs the ones with the shutter release built in, all purchased from differing sources. I have the correct cable release for them but I cannot get the button on the film back to depress and activate the shutter. I have tried all of the following but with no luck, the button on the film backs will only depress about 2mm, and seems to be in a locked mode.
Settings tried
Film loaded/not loaded
Dark slide in the stored in rear of film back position
I cannot see any secret catch to make this work. The only catch visible is the one on the base of the film back which unlocks the cable release.
I don't want to force anything so has anyone any ideas please.
