FTZ adapter with face/eye tracking

[TROGDOR]

Hello! I went back to photography last yeat after ~15years of hiatus.
I then bought a used Nikon D7200, a several second hand lenses, and have been loving it.

I'm thinking about upgrading to a mirrorless though, mainly for the face/eye tracking AF.

My lens collection is quite nice, so of course I have been thinking about keeping the lenses and use a FTZ adapter.

That's where it gets confusing for me, as people seem to have wildly different opinions about the adapters.

The camera I am considering is the Z6 ii (second hand). My main (and very loved) lenses for portraits are the AF-S 85mm 1.8Gand AF-S 50mm 1.8G (both are FX).

Does using the FTZ adapter make the face tracking + AF worse in any way, as compared to using native Z lenses?

Any other things I should be thinking about before purchase?
Thanks a lot if you have any comment or hint

I have a Z7ii and a Z8 that I use with an F mount 200-500 F5.6 using an FTZ. The AF tracking works quite well with the Z8 and this adapted lens. I shoot mostly wildlife/nature photography which is particularly demanding of AF. I found the AF for wildlife in the Z7ii to be somewhat disappointing. It seemed to work OK for people, but I rarely shoot that type of image. If you are looking for superb AF tracking, I would suggest holding out for a camera with an Expeed 7 processor, especially if you are shooting wildlife. The animal object detection for the Z6ii is designed for cats and dogs. Both the Z6ii and the Z7ii have dual Expeed 6s. The Z50ii, Z5ii, Z6ii and the Z8 and Z9 all have Expeed 7 processors. Perhaps someone else using the 6ii will chime in on how well their Z6ii works on AF.

I believe the newer Z lenses are probably better at AF tracking than their older F mount counterparts, but, in my experience, the F mount lenses adapted seem to work well and doubt it is a large difference in most cases. Keep in mind the adapter has no optical elements, it is merely a spacer with the correct mounts and connections.

Should be no problem at all. Z-mount lenses will normally have some advantage being newer and smarter. I think having a wide aperture lens helps most so the body can see the scene better.
