I have a roll of film in the old rangefinder from eBay that's getting sent back. I've shot eight frames with it, but I have no interest in finishing the roll. The camera needs to be sent back, and it's clear that it has some issues. I want to retrieve the film and use the rest of it in my Ricoh, but am curious about the Yashica shots, so here's my idea: Rewind the film in the Yashica, Load the film into the Ricoh, Advance to the ninth frame at f/22, 1/1000 shutter speed, and with the lens cap on, Shoot as normal for the rest of the roll. Now that I think through this, there's really only one issue: I need to rewind the film far enough to cover the frames, but to keep the leader out so I can reload it into the other body. Any idea how to figure out when the leader has detached from the winding thingy but isn't back into the canister yet? Thanks in advance for all of your help.
