mamiya RB67+Sekor 35mm lens

Hello,

Anybody know if I can use a Sekor C 35mm for 645 to my old Mamiya RB67?
Thanks
P.S. And if it's possible -any problems with focusing ?

I am pretty sure that is not possible (even though I have never used neither) first the lens would probably not cover the larger are and second, the film-to-flange distance must be large with the RB so even if you would mange to mount it via some adapter (which probably does not exist) you would not be able to focus to infinity.

But I hope somebody with more experience will reply

Different lens mount, different shutter system (?), shortest rb lens is a 37mm. Depends on how close they made that inifinty focus on the rb body.
