This is probably going to sound very silly. But I accidentally hit the film rewind button when squeezing my camera back into the bag. No problem if I had already finished the roll, but I sitll have got about 10 exposures left on it.
So... Am I doomed to waste those remaining exposures and rewind the entire roll? Or the moment I **** the film advance lever, the "catch" (is there one?) will engage again and I can happily finish the roll of film.
