Asher, I got mine refurbished, today I had a demonstration from dealer, and it has few hundred actuations what it means that its almost new or probably a demo. This one is black, the feeling is swiss army knife solid, compact like a rock it is really elegant and minimal. I came in a black pelican case with Firewire cable, two batteries and a slick dual battery charger, free software updates and one year "hot" warranty. If something happens with the back the give you one while they fix it. Sensor cleaner 1G CF etc. Total $14.000
Menus are simple easy clear and to the point. The program has a Mac OS/Photoshop look and very intuitive, when the camera is connected to the cable the program "sets up" the back and you can shoot and view just details of the raw files at 100%. This is like converting just small parts of files from raw just to check IQ.
Regarding to Mamiya or not Mamiya is a complete different topic, I have always had something from them, C330 twin lens reflex, RB, RZ, an now 645. What the technical guy said to me is that Mamiya is very much like Hasselblad (Fujifilm), -- Hx zooms where better -- and that it was "overpriced" Im happy with mine because it is a lot smaller as a system, and very easy to hold. He showed me the Sinar 645 system and (it was enormous in size and price)
The viewfinder of the 645 is very good, even with glasses you don't touch the camera if don't want to see full frame, it is simple, not a lot of features, and AF works, but not as fast as some 35mm. There is no rotating back a la RB/RZ, so you rotate the camera to portrait, but it is no different than with my Fuji S2 (no vertical grip)
I'm so happy, now I have to find a way to pay the loan.... and insure it etc
Ah, they also give free training
