When asking if the 1.9 is THAT much better than the 2.8 ... the question that comes to mind is \'Better in what regard?\' ...
... sharpness, DOF isolation, bokeh, transitions, light gathering, color, contrast, aberrations, tonality, mfd, weight, portrait use vs. landscape, etc.
\"Better\" sometimes is really code for \"In what ways are they different?\" (that would justify / warrant the $$$ diff) that would make / not make them \'better\' for my shooting style.
In a simple example alone, the N versions have different coatings that yield a bit more contrasty images, while the C versions have a bit less contrast. If you want contrastier imagery ... the N is likely to be better suited for you style. If you want a bit less contrast (still very nice and easily bumped in post) file so you have a bit more tonality lattitude in post, the C might be better suited.
In the case of the 80mm I\'ve got the 80/4 Macro C version, so I can\'t comment on the diff between the 1.9 vs. 2.8 ... but it might be helpful to clarify for others where your interests / utilization / concerns are with the 80mm M645. My guess is that unless you have a specific reason for wanting the 1.9 (other than the obvious f-stop) the 2.8 will likely serve you well (for little $$$). Shooting the M645 glass is a bit different from 35mm glass ... but for me I find the M645 glass to have what I would call a very neutral drawing style ... rather than a \'Mamiya Look\' akin to an Oly look or a Zeiss or Leica look, etc..
For me, I\'ve got some Zeiss (35mm registration) for contrastier shots ... and Mamiya (M645 registration) for tonality shots.
