Question

How do I load the film into a 35mm MV1 Pentax camera?

Answer 1

There should be a release at the end of the camera opposite the hinges which allows the back to open. Inside there should be a reel that stays in place and a curved pocket of the size to take the film cartridge.
Something will need to be pushed, usually, to release the film advance from being only one frame at a time or you will have to trip the shutter. Do a film advance and watch the builtin reel to see which way it turns, usually going down on the side toward the middle of the camera.
Lay the cartridge in the pocket You will need to pull out enough film to reach across the back, usually far enough to have the holes on both sides fit on the sprockets if they are there. Fit the tongue of the film into the slot in the takeup reel and advance the shutter to pull the film around. Tighten it somewhat, hold the cartridge down and close the back. You will then have to advance the film so the exposed film is beyond the shutter opening. I commonly tighten the rewind handle so I can see the film advancing as I have one camera that tends to lose the grip on the tongue sometimes.
Before openning the back again, the film must be cranked back into the cartridge.
