Mark, thank you This is not so clear in documentation that is available. Had I known the strength of the face/eye AF with the D810/D750, I would have moved sooner. I have come from Canon 5DII, Leica M9/M240 and A7 series. This is not really highlighted anywhere, as most people including myself only thought the A7rII had the eye/face AF feature.
I have the eye/face AF feature with the Fuji XT2, but it is not in the same league as the D810.
No problem. Sometimes the included literature isn't overly clear.

I took a series of 12 shots, and each shot is in focus, even though the "displayed" focus points were showing the chin, cheek and forehead between different shots. It is like you have to ignore what the OVF AF points are displaying and trust the algorithm !
The OVF points are an approximation when you are using the modes that move them around freely. Same thing when using 3D AF, the little square can lag behind the actual point of focus giving the impression that it can't keep up, but the actual image is as intended. I imagine on the new bodies (D5/D500) which such tight AF configurations it's even more difficult to tell where the AF is just looking at the red square.

Great thread...could anyone comment on D500, regarding this feature(s)?
The D5/D500 eye/face tracking is the best available thanks to the new CAM20K AF module, the much higher resolution 180K pixel RGB meter (which is what it uses for this and allows it to lock onto finer details more precisely), and the Expeed 5 processor (along with the dedicated, separate AF processor). The 3D tracking also relies on these components in concert to "lock on" to the target and has also gotten so good that you hear of more and more professionals trusting it instead of their "old faithful" settings.

Has anyone tried this with a zoom, like a 70-200/4?
It works pretty much the same no matter what lens you're using. AF in general is typically faster and more accurate with telephoto lenses as well.

Interesting thread! I had no idea that Face Detection worked so well with the newer Nikons. As someone who has thought about the D750 for a year, this is good news.

Has anyone to date had good luck with this feature or features using a non-Nikon lens, such as the Sigma Art series? I'll play around with it, but just initially curious.
This I'm VERY interested in. The Sigma 35/1.4 will be my main lens if I get a D750. I'd really appreciate if someone could test how FD works with this lens.

I will try and test this weekend with the D750 and 35 Art
Follow up:
The D750 with the 35 Art works well with face/eye AF so far.

Face detection is all in the body - as mentioned earlier it doesn't really matter what lens you use. If the lens is good on the body without FD, it will be good with FD.
