Is this only in earlier versions of the lens, or is this all of them?
I ask this question because it appears the 85mm f/1.2 Nikon just released is suffering from the same non-asymetric resolution curve. I experienced this on the 35mm f/1.4G, and 85mm f/1.4G and don't want to go back to those types of lenses again.
Appreciate any feedback you can provide.
I'm also seeing these reports and reviews, and I found Camaralabs to be a reliable source of information. However, in this case, the reports just do not fit to my own experience. My 50mm f/1.2 S is sharp at close distance at f/1.2, i.e. at least as sharp as the Camaralabs example at f/4, as far as I can see.
For the image below, I have set manual focus to minimum distance and used a Novoflex Castel-Q to adjust the distance. The 10 euro bill is not completely inside the focal plane, as you can see. Focus/distance was set to the center of the image.
