Why can't they make all f/1.4 lenses sharp at 1.4 since they are intended to shoot at f/1.4 to f/2.8...not at 5.6!?! IIRC, that was the profile of the Nikon 85mm f/1.4 D...sharpest from 1.4 to 4.0 (vs. the 1.8 version which was sharpest from f/4 to f/8).I buy an f/1.4 lens to shoot at 1.4....why don't they optimize them for that and make them that way??
You mean absolute sharpness or relative sharpness? I got an f1.8 that shot as sharp in the corners as a (bad) zoom at f8.
If I wanted to work principally at max aperture I could have a noct-nikkor for $$$$
Manufacturers currently seem to be optimising the new G range or Sigmas to perform as best as possible wide open, but give ground on geometric distortion.
