from Ken's page:

The adapter only works properly (autofocuses) with Nikon's newest lenses, which are those with built-in AF motors (AF-I, AF-S and AF-P). With all other lenses autofocus does not work. AF and AF‑D lenses become manual focus only.

Manual-focus F, AI converted, AI and AI‑s lenses on the FTZ have 1.) no automatic diaphragm control so you have to open and close the diaphragm manually for each shot for precise focus, and 2.) absolutely no communication between camera and lens so the camera, meter and EXIF data have no idea what aperture you're using, and 3.) the camera has no ability to set the taking aperture so there is no Program or Shutter-priority modes with these lenses. 1984's Nikon FA or any FX DSLR do all this and so much more with manual-focus lenses, but the FTZ is a zero and you may as well use a cheap passive Chinese adapter for manual-focus lenses — it will have the same functions and save you over $200.

The sad reality is that the longer-term Nikon shooter you are, the less you will want the FTZ because less and less works with older lenses. The FTZ is really only for people with recent lenses. It does not do Nikon's great legacy proud, but for most normal people with lenses less than ten years old all should work great. Just don't fall for Nikon's deceptive marketing implying that older lenses work well — they don't.
