Katgut, you've misunderstood. I'm not advocating the Fuji, nor denigrating the Mamiya 6.
The point is that these are simply two different (types of) cameras, and any 'comparison' is only useful on an individual basis, relative to the ONE consumer's personal needs. It's silly to assert that one is "infinitely more useful" than the other. It's like saying a Leica is infinitely more useful than a Rolleiflex. Having said that, i owned the Mamiya 6, and also decided not to pay the...amount they are asking for the new Fuji. For me, it wasn't so much the price as a combination of the price and the 'delayed' release. I bought a Bronica RF645 instead.
No, the Mamiya 6 doesn't do 6x7. Is that a big deal to you? Apparently not. But, in the context of the question to which i was responding, it seems significant. "How could this be better than a used Mamiya 6." It COULD be better if the user wants 6x7. That's simple. The other points i mentioned remain unaddressed.
1. The Mamiya 6's 75mm bokeh IS pretty awful. When you can even elicit it. Minimum focus distance is pretty long, and the lens is pretty slow. When you do manage blur (at least in the 'portrait' situations in which i used it), the bokeh is ugly. Maybe you shoot landscapes. Maybe you don't look at bokeh. Whatever. As i always point out, Adam Jahiel makes some gorgeous images with a Mamiya 6. But, bokeh isn't a component of his work.
2. For some people, folding flatter than the 6 could make the Fuji "better" than the Mamiya.
3. This was meant to be an earnest question. WHO IS repairing these? More importantly, though, and in this area i should have been more specific —*the issue is of repair parts for the winding mechanism. By many reports, these parts seem to be unavailable. Doesn't much matter how competent the technician if he can't get the necessary replacement pieces.
4. I strongly disagree that a person would "never notice the difference" between 6x6 and 6x7. If you're interested in the new Fuji because it can shoot 6x7, you want horizontals. Cropping a 6x6 to horizontal means a pretty significant loss. Obviously, it's not the end of the world, and as i said, i bought a 645 camera, but there is a difference.
