    Hi all,
    After searching a bit, I can't find anything related to this issue :
    I am trying a new back on a contax 645 but the back is not advancing the film to frame one, the viewfinder show 00
    if I change to another back wit an insert loaded, it will advance the film.

    This is really annoying as the back looks like new...

    Thanks,

    Luc
