Nine Lives Lost.
For those who are interested in such things, Nikon Z7, 50mm S, ISO 64, f/1.8 @ 1/30 sec.
I recall you shot this subject before. Prior to the Nikon. Would be interesting to compare. I for one, think that this looks absolutely horrendous, and I'm not talking about the subject, but about the rendition. No, Rob, this is not a critique. This is an evaluation of the lensdrawing, which, in this image is just utterly horrible. There is some kind of weird halo around the tail and back. This may not actually be the lens btw, but perhaps the postprocessing sharpning. This may also explain the rather deteriorating focused drawing, which has the type of ringing one used to see in old Canon files trying to overcome an antialiasing filter. Then the curvature in the lenses' field of focus is disorienting.
I know this lens is sharp and should have a good oof drawing, so something is wrong. ( <--- See, Rob, evaluation, not critique).
