I can't wait for your comparison report. I got a folder a long time ago (can't even remember what it is right now) that stays on the self and was only used once to verify it's operation. Glad to see there are around 4 or 5 of us here who still have/use our Mamiya Press cameras. I need to get it out and run some film through it.
For the record, I think other than getting a new Fuji camera, you will have to have any camera CLA'ed as a minimum anymore since most of the medium format equipment is 20+ years old.....if not older. Crap, I just figured out my Super 23 is around 45 years old.....wow.
