I realize ahead of time that this is somewhat off subject but I am sure some members of this board are familiar with RB67 cameras. Will the RF backs for 2x3 work with the RB. I know that some Mamiya backs will work with a 2x3 Grafloc. I have a couple of nice 6x7 backs which would be nice to be able to use on an RB if that is possible. They are Singer backs and in nice shape.

The answer is ......Yes, with some loss of functionality of the RB such as accidental double exposure prevention, shutter lock when darkslide is installed, graflock slide locks not released when darkslide is installed, making mid roll back changes more difficult, and the Graflex backs do not have the unexposed/exposed window that the RB back has. I suspect a 6x9 back might have problems also.

That answers the basic question. I have access to an RB and it would have been nice to be able to do mid roll changes rather than having to burn a whole roll while using it, beast that it is. May try it anyway just to see how it compares with my Century for functionality. I'm always looking to expand my stable of cameras. Really need to get rid of a few before wife decides to lighten her burden by getting rid of me.

The Mamiya RB is a heavy beast more suited for tripod work than hand held. I sold mine (cost of lens and accesories influnced my desison), and a portrait studio at the nearby mall uses them.

Since both film and processing are relatively cheap I tried the old RF backs on an RB67. The interlocks to prevent double exposure, shutter tripping with the dark slide in, ect do not function with an old back installed. The insallation is just like that for a Mamiya back. Mid roll back changes are not only possible but easy. The sole draw backs that I see are the same as using an RF back on a Graphic. You really have to think. Film winding and slide removal are not thought about for you as they are with the Mamiya backs. That said, all the drawbacks associated with Singer or Graflex backs still apply, shoddy spacing, poor flatness and no source of new parts. Too bad I did not get a chance to try an RB back on my Century. Sure enjoyed using the camera though. Results were pretty good.
