And as I just found out: If you have problems with the film not advancing in your Kiev camera and it's because the sprockets are not turning make sure the pin that disengages the sprockets (to allow you to rewind the film) can move freely. This wasn't the case in my Kiev 4AM just now and the sprockets only turned now and then.

PS: Really, really no 36 exposure rolls? Too bad as I have about 30 rolls of 36 exposures in my fridge :/
