Two comments... the 135 and 180 Mamiya lenses are SOFT.
Perhaps by design, for 'portrait' photographers. I have
a 65, 135 and a 250, the 135 is definitely soft. The other
two are just fine as far as sharpness goes, even wide open
(or as near as I get to it). I have heard that the Mamiya
180 mm TLR is also soft.

Also, I find that the ground glass screen has enabled me 
to judge my composition far better than eye-level viewing.
I think the Pentax 6x7 is meant primarily for eye-level
photography, if that's the case I see that as a drawback.
