They appear identical. Probably, to correct the outward bending FC Cosina should adopt a more complex scheme (leading to a larger/heavier lens).
Right. The question is whether we can trust the optical scheme of the Z version. Did the marketing department actually get the new drawing?

If the drawings are completely identical, then what they are actually saying contradicts the drawings:
"Optics optimized for the image sensors of mirrorless cameras with the Nikon Z-mount are implemented."


As I understand it, it is possible to correct for the thicker sensor glass by subtle changes to the lens elements and there spacing that wouldn't show up on the lens diagrams. I could be wrong, however.

What I do know is that I cannot see differences between the diagrams for all the Nokton lenses that are VM and Sony E and yet the Sony E lenses perform better on an unmodified Sony camera.
