[Informal] Mamiya M645 lens testing on D7100

In case you are interested, I did some 'informal' testing of my 3 Mamiya M645 lenses on my D7100 body today (since I can't find any information for these lenses online). Here's what I found as sharpest and when -

Mamiya Sekor 35mm f/3.5N - sharpest at f/16
Mamiya Sekor 80mm f/2.8N - sharpest at f/4
Mamiya Sekor 150mm f/3.5N - sharpest at f/11

It's interesting to note that the 35mm f/3.5 appears more suited as a landscape lens (which you would expect). And the 80mm lens is the sharpest of the three (which matches what I've heard from elsewhere).

Again, this wasn't scientific :) I simply compared identically composed and focused shots with each lens in Lightroom. How does this compare to anyone else's own experiences with Mamiya M645 lenses?

Thanks,

Ron.
