Hi All
Are there any alternatives to a graflex rh12 holder that fits the mamiya rb67. I would love to be able to shoot "native" 6x6 with it instead of having to crop down from 6x7. I saw an older graflex 22 with a lever wind, on ebay, but does that have the important extra rollers to help film flatness or not? I am aware that the standard graflex 22 with knop doesn't.

Mamiya 6x6 back? Not that common but they exist.

But a mamiya 6x6 back makes a graflex rh12 seem like something you can pick from trees.
I was hoping there were other options. The reason I'm asking in the first place is, that I've been looking for a rh12 back for a couple of week now, and havn't been able to find one.
Best Regards

Mads,

There is a difference in film plane I believe between the Mamiya backs and the rh backs. That is what I was told and looking at the 2.25x3.25 sheet film I shoot in Grafmatics on the rb67, I think it's so. They are just not as sharp as the roll film I put through the rb67 in Mamiya holders.

And no, I have never seen a Mamiya 6x6 holder, but if I ever do, I will snap it up in a heartbeat. In the meantime, 6x6 gets shot in my C220.

In general the lever wind backs do have the extra rollers. Dont know about alternatives to the graflex (Id chase those who made 67 and 69 backs: linhof, horseman etc)

A quick Google suggests that a 6x6 back for the RB has never been made by Mamiya. RZ had 6x6, but not RB. Is there room to place a mask in front of the film and another on the ground glass?
