I bought a RB67 Pro SD. I check on e bay and there are a bunch of different lenses for the RB. Will any of them work or is there a certian kind I need to get? I have noticed some that have a KL, what does that mean? Thanks

I may be wrong, but I think you want to shy away from the KL with Pro SD RB67. I've heard it works but it limits something. I got my first RB in 1981-1982 and just remember somewhere along the line that Mamiya rep at a camera shop said the Pro S works better with the 'newer lenses'. It probably has to do with focusing at full aperture and the stopping the lens down after the focusing. Much time has passed and I've forgot the reason.
