Photozone.de
0.14% barrel distortion ie. almost nil!
1.3EV vignetting - much better than the
Canon EF 85mm f/1.2L USM lenses
very sharp centre, soft corners due to considerable coma, centre sharpest at f/4, edge-to-edge sharpness best at f/5.6-f/8
minimal lat. CA 0.6px
bokeh a little nervous and shows long. CA
a bit tricky to find the exact manual focus due to the very short focus path

minimal 5% astigmatism
coma worse than the Zeiss 1.4/85 and the Nikkor AF-S 1.4/85 but a tad better than the Canon 1.2/85, but the best coma correction is the cheap
