Length of "Imperialist" vs Soviet Film Casettes
I did the first roll of film trought my Zorki 4 and realised that the film was exposed a bit diagonally. I found that the film casette is positioned to low at the bottom of the chamber and has some slack.
I suppose that the original soviet film casettes were a bit longer than the western ones. So I want to put a washer under the film casette to compensate for the different length.
Do you know how much difference is in the length between this two types of casettes?
