p.1 #1 · p.1 #1 · Sigma 85 1.4 HSM focus way off on some focus points


When I first purchased my D810, the focus seemed fine on my 85 1.4 (albeit a little inconsistent), now, it seems my Sigma 85 1.4 HSM focus is WAY backfocused more than in-camera adjustments can fix on all focus points except except the bottom left and bottom center points (I use the 9-point system on my D810).

What's going on? Is this something Sigma can even fix? D810 works fine on all other lenses.

Have you tested the optical performance of the lens to check it is OK in those areas?
