I bought a Mamiya 645 1000s that needs work...
I knew what I was doing, but its the gambles we take.
Of the few issues I see with the camera, so far, the issue I want to tackle first is when winding it doesn't stop at the next frame. It clicks past, and it doesn't let you shoot unless the line on the winder is at 12 oclock.
If you do a full rotation of the winder it does a click/has pressure, but then passes beyond it. Unless you happen to be pressing down on the shutter button as you're turning that point. The way around this is you do the rotation, then put it on Multi, do another rotation to 12 o clock, then you can enter the space that allows the shutter to be shot.
Otherwise shutter speeds seem fine, the battery is new and fresh, not sure if the insert has an issue. I just put an old expired roll in it and it didn't change anything.
The other issues don't correlate, like the lens blades stick a little and I'm testing to see if there's a battery drain.
Thanks in advance. And if you don't know what's up, a video to someone opening it up would be nice!
