It's a 6x9 holder that takes 120. The graphics don't have rotating backs but there are tripod sockets on two sides so you would rotate the camera instead of the back. I don't have any sheet film holders but they are out there. They both have movements (rise, fall, shift, drop bed). I ran a roll through #1 about two weeks ago and everything functioned fine. I haven't shot with the second camera. I bought it for the lensboards and ground glass back but the seller assured me it was 100% working and I don't have any reason to doubt that.
