Wrong. "D" has NOTHING to do with the AF system. Many D lenses are also AF-S and work great with the Z and FTZ combo. In fact, ALL AF-S lenses are also D lenses, it's just that Nikon dropped the D designation once all their lenses carried the D communication chip in them.
No "AF" lens is compatible with the FTZ adapter as all Nikon AF lenses are mechanical screw drive units with no in-lens focus motor, as required for the FTZ to function with them.

This is a direct quote from the Ken Rockwell web site:
"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."

I'm not saying his use of AF-D is correct and you are wrong. I am just saying that to those of us who are not Nikon lens historians, it's easy to see how there was confusion about the lens naming. So thanks for bringing this to our attention and let's leave it at that.

Now everyone go buy a Fringer EF-Z adapter and we can forget about this AF ..... D stuff forever.

Equally to the point, Canon avoided all this confusion by making a complete change at once {even though it made all of their existing lenses 'obsolete' at once}. Nikon and Pentax preserved a degree of compatibility by making a series of small changes .... and sewing all this confusion.

Really, I'm ignorant because I said D Nikon lenses will not work on Z models? My favorite Nikon Lenses are the old 60mm and 100 mm D lenses. Nikon says they will not work on Z models, I have tried them on the Z6 and Z7, guess what, neither one auto focuses on a Z model.
When I posted that D Nikon lenses would not work on a Z, I was trying to help the OP, I did not expect to be called names for trying to help someone out. Below are two of several older D Nikon lenses that I own that will NOT AUTO FOCUS on a Z. Please keep your name calling off this site, it does not become you.

Really!! Here we go again? That's all you have to say to someone who was trying to help out the OP so he would not be disappointed when he tried to put a AF-D Nikon lens on his Z50 and find it would not auto focus. You are a business man who sells lots of photographic equipment, and you post this without a reasonable explanation? Below are two of 6 Nikon D lenses I own that Will NOT AUTO FOCUS on a Z50.
I may not have been 100 % correct about all D Nikon lenses, but I was only trying to help the OP. I did not give him a thumbs down as sign of dismissing someone's helpful post. This is just one of your many negative posts on this site. I would have thought better of a businessman.

Again, most of your posts are really helpful, but then you post something like this, do you really believe you are being helpful here?

Nikon makes an AF Zoom-Nikkor 80~200 f/2.8D ED lens. They also made an AF-S Zoom-Nikkor 80~200 f/2.8D ED lens. With the adapter, one will autofocus on a Z50, the other will not. I should think that any Nikon user ought to know why.

While I was not addressing you with that comment, maybe I need to explain. Ignorance is simply a lack of knowledge having nothing to do with intelligence. We are all ignorant of many things.

You were ignorant of the fact that some lenses with the D designation will work just fine on the Z bodies. The D means the lens reports distance back to the body which is used to assist in determining flash exposure . It has absolutely nothing to do with auto focus.

Now there is one less thing you are ignorant about.

It is the AF designation that lets you know that these lenses will not auto focus on the Z bodies. In all their infinite wisdom Nikon put the unrelated D far away from the AF on the lens barrel.

Unfortunately too much incorrect, or incomplete, information is spread around the web with the good intent of helping.

Have a good day.

Flash exposure is the secondary purpose, since more photographs are taken without flash than with. The function of the D chip is well explained on pages 74 and 75 of the original Nikon Compendium. A Google search should also be educational.

Unfortunately that is true. I think some of the responsibility lies with Nikon, which has developed their own language, a language which must be learned.

For example, I had a misunderstanding yesterday with a well-informed Nikon user. I used the term 'AF', meaning 'something capable of auto focusing', and he heard 'a lens which uses screw-drive and is therefore dependent on a body's auto focus motor', because of this language difference.

You are absolutely correct. But, I don't think it is limited to Nikon. We only have 26 letters to work with and more and more we depend on abbreviations. I get emails sometimes from much younger relatives and I have no clue what they are talking about. I'd be afraid to switch camera brands for fear I wouldn't understand the user's guide.

Have a good day!
