I currently shot with several different medium format camera systems and have for over 35 years. One would think, I would know or have found the answer to this question by my by now.

Does anyone know for a fact, if the RH12/24 singer or grayflex film backs will mount to the RB Pro, Pro S, or Pro SD System camera and actually be a usable entity? I would like to be able to do 6x6 format on this system thus eliminating a couple of other complete camera systems I have been totting around...
