    A while back I bought a new "old stock" 70mm film back for my Mamiya RB67 Pro-S camera. It's new in box.

    I have a question....

    Seems that WHAT film I DO see is NON-perforated.

    Opening up the back, I see sprockets at the top on the left hand side only. The manual says it uses perforated film. However, the sprockets are not very big and I assume they're for alignment only.

    Can I use NON-perforated film in this film back?

    If not, WHERE do you find perforated 70mm film? I'd really like BW film vs color since I can process the BW film and have never processed color. I have a Jobo tank and have a pair of 70mm reels purchased and awaiting their arrival.

    Thanks,
    Steve

    It's getting very hard to find affordable 70mm film. Kodak makes 70mm film aerial film which you can find on the B&H website (special application film). Very pricey though.
