Just got a Mamiya 645 Super with two film backs but have run into a problem.

The film back attached to the camera is missing the darkslide (so it won't let me remove the back from the camera)

The extra backs I have have the darkslide installed in them (so I can't remove the dark slide w/out it being attached to the camera)

So... How can I either a) remove a film back that has no darkslide on it or b) remove a darkslide w/out it being attached to the camera?

    There must be some sort of release pin/lever that operated the interlock, have a good look at the backs... – Digital Lightcraft Nov 18 '15 at 8:35
  • does the 645 have these tabs? – dav1dsm1th Nov 18 '15 at 13:59
  • @dav1dsm1th Yea the 1st time I loaded that video I was like "Yes, this is it!" then I realized those are different film backs :p – Shizam Nov 18 '15 at 20:11

Figured it out, there is a tiny black button (that looks like a screw) next to the bottom right screw in this photo, that is the button to press to release the slide. I kept pressing the giant button in the upper left thinking that clearly had to be the release :p
