Tests
Scene 1 and 2 where shot on the Sony A7R2. Scene 3 was shot on the Nikon 1 J5. The pixel density of its 20 megapixel CX format sensor is roughly equivalent to that of a 150 megapixel FX sensor. But of course you can only test near the center of full frame. Still, I think it is interesting to see how the lenses would perform on a hypothetical 150 MP sensor.
The 1.4/5.8cm Nikkor was only included in scene 1. In addition, the 2/50 Nikkor and the Sony lens could not be included in scene 3, because adapting Sony E lenses to Nikon CX is impossible, and the 1.4/5.8cm and 2/50 Nikkors do not fit the FT1 adapter because of protruding rear mount elements.
All photos taken at base ISO using a tripod and a remote release. On the Sony, EFCS was enabled. Developed in Capture One 11, no lens corrections applied, output sharpening disabled.
I did some additional shots at f/5.6 for scene 1 where I focused on the outer midfield crop instead of the center. Comparing these to the center focus images shows the effect of field curvature (quite drastically, I think).
