Facebook being what is is, I can't post the link to Clyde's comments, so I've copied the quote here:

"Sunday I took off to Myakka to test out a few lenses. The weather wasn't
really any good for photography, but I wanted to test them before my
trip to Bozeman MT where I have an exhibit in the Rocky Mountain Museum.
Using my Sony a7R digital body, I took the same photo at Myakka
using the Cambo Artus with the RZ Mamiya 75 shift lens, then with the
Cannon 17mm, then the Voigtlander 15mm, and then with the Zeiss 15mm
lens. My conclusion has be introduced by saying that my eyes aren't
what they use to be, and that none of this was done scientifically.
Anyway, when I put the images up on the computer screen the two best
lenses appeared to be the Cannon 17mm and Zeiss 15mm. Hard to tell the
difference. Then the Voigtlander, which was so close to the other two
that it wasn't worth saying it was to much different. As for the Mamiya,
it too was very sharp, but in a much different way. It looked
like…well, a photograph I had taken with film. It was sharp enough for
me to enlarge it to a ten foot print on my computer screen and still
look sharp, but it didn't have that HD quality to it that digital lenses
have…it isn't a digital lens so it behaves differently. It's hard to
explain.
Now that I know what each lens will do, I'm ready for some "real" photography!"
Clyde's been experimenting with digital photography, because he felt he couldn't carry around his large format cameras all the time. But an interesting discussion of experimenting with lenses from film cameras to eliminate that "Digital Look", something that I also find unattractive.
I think you know what I mean, that "unnatural sharpness" of things your eyes can't actually see.
Remembering that people are not best served by HD television, why should all of your photography have that HD look too?
Thanks for the Test Clyde............Glad that the Mamiya Lens looked "real":
