Rod, out of curiosity, what is the price for this new mount? Also, when will it be available. As always, thanks!The 47mm can be used, but very tight on many DSLR/Mirrorless bodies.
Also, Arca-Swiss is now offering the new rotaFoot, which is an even better mounting for the camera and lenses as it does not require DSLR removal to change orientation.
The rotaFoot is very thin and uses the same bellows as the setup to use the L bracket, but simpler and more precisely square to the front standard.
Someone above commented that the 55mm had issues with 20mm shift, but what aperture was the image made at?
To get the best image quality, and maximum movement, the lens needs to be stopped down to F11-11.5 on a GFX50, and about F8-8.5 on a 100mp unit. While you can stop down more to make anything a comparison will show the quality in comparison is around these parameters. a 90mm and longer lens, will give you the ability to stop down another stop from the above parameters. So 50mp MF can produce wonderful images at F16-16.5 with a 90mm lens and longer. And with 100mp sensors you can get to F11-11.5 wit a 90mm and longer lens.
We have tested a 100mp Phase back at both F11 and F8 and a 40mm Rodenstock. When compared with no adjustments, the F8 image was significantly better than the F11 image.
Then we ran the F11 through Capture One's tab for cleaning up diffraction, and it got a lot better. But it still was not as good as the untouched F8 image.
Just some observations.
Glad to see people are striving for quality.
