I finally made the leap!
I just thought I would share with all my leap into medium format land. I have recently purchased from a friend (a good photogrpaher who has gone completely digital) a very well cared for Mamiya system. It includes: RB67 Pros S body with Beattie Intenscreen, Prism Finder, 2-120 film backs, 1 Mamiya polaroid film back, 1 NPC polaroid film back, 90mm Mamiya-Sekor f/3.8, 180mm Mamiya-Sekor f/4.5, lens hoods, Tiffen #8 & #11 filters, cable release, and bag. Price------$1,000.
I've been waiting for something like this to come along for a long time! guess patience is virtue.
