70mm film back question
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.
No, your back cannot use unperfed film without modification.
As to availability:
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.
