I had a Mamiya 6 with all the lenses. Ergonomics are just perfect, really you can't get a better handling 6x6 camera, weight, balance, the lot. I got rid of it for two reasons. One was the slightly sticky film advance made me uneasy of an impending repair bill (guy who bought was aware of this and paid accordingly before anyone asks). Two was that a 75/3.5 that focuses to 1m is just not that good for anything resembling a portrait (apart from environmental ones). As far as image quality goes, I think this was the sharpest I've ever experienced, (and I've owned Hasselblads).
