I recently purchased a Mamiya 645, and I was told from the fairly reliable seller that it was recently CLA'd. Upon receiving the camera, everything looked great, so I started to fiddle with it a little bit. I flipped the mirror lock-up down, and then obviously, the mirror went up. However, when I flipped it back, it didn't go down all the way, only about half an inch. As I understand it, the shutter won't fire unless you have film in the camera or if you have the switch set to multi, but I cannot get the shutter to fire when I set it to multi-exposure. I am not sure if this is because the mirror is stuck or another reason, but I would love some help. Nothing seems like its sticking, it seems mechanically stuck, and I have a brand new battery. Oh, also the film advance lever moved slightly forward when I got it, but now it doesn't move. Hopefully, this made sense, and feel free to ask me to clarify anything if need be. Thanks!
