Nikkor 85mm 1.4G focuses in the wrong place if you stop down to f2.8 or f4. If you are taking a headshot 1-3m away and focus on the eyes, AF puts focus 1 cm inside the head. Eyes will be totally blurry. How does this lens have such a good reputation when it fails so basically at its core task. WTF were the designers thinking. I am on a film camera so live view focus is not an option. Unusable shitlens. https://phillipreeve.net/blog/review-nikon-af-s-85mm-1-4g/#Focus_Shift the 105 1.4 is even worse https://blog.kasson.com/d850/nikon-105-1-4-on-d850-cdaf-pdaf-focus-shift/ also wtf is with these captchas it is getting too hard to post here

old nikon problem, it's a 1.4 issue, the 1.8 lenses work fine. the fast long primes also ghost quite a bit. also works on the f/2 dc lenses

kasson measured the 85 1.4 G here: https://blog.kasson.com/the-last-word/another-medium-tele-test-otus-nikkor-focus-shift/>AF puts focus 1 cm inside the head it's not 1 cm inside the head, rather more like 5-7 mm, since that ruler is being photographed off-parallel. whatever amount it is, stopping down seems to make it systematically miss focus completely.i guess film people are stuck with the 1.8 G, since no live view = no way to correct for it.if i have no way of telling if the eyes are in focus in headshots then it is useless to me sadly idek what focus distances + apertures it will ruin real life shots at but all the tests are a bad sign.

You need to use AF fine tune on DSLRs. Not a problem on mirrorless.
