Hi all

I am the happy owner of an RB67 and would like to shoot 6x6 on it. I know I can just crop when printing but the extra frames and the natural vignetting would be nice to include. I have heard that some backs WAS produced at some point? Also Ive heard talks about a RH12 Filmback (graflex I think) that should be able to fit the RB system?

All the best,
