That's an AF-S lens (yes, AF-S D, I know). Did you read my other posts?

No, because it wasn't meant as an explanation of all those abbreviations for new users of the system, but as a (fairly typical) abbreviation used by those already familiar with the system.

[...]

The way Nikon have structured their lens naming system means that this subject is always going to be complicated. Sadly, attempts to simplify it (even when well-intentioned) tend to create confusion.

I could only repeat myself, so important parts highlighted in bold letters instead.

...but still: even on that list, an 'AF D' lens is a screw-driven lens

Yes - but so are AF and AF G lenses.

Yes, true. But the discussion was (at some stage): do "AF-D" lenses have built-in motors? For you and me, they don't, right? And also for many others. That was my whole point.

I only posted the image to show the markings, not to dispute anything you or anyone else has posted. It was easier to just reply to the last posting on my cell phone. No arguments from me.

In this thread, I think the confusion began when someone said:

You sure the lens is a D lens?

Those do not have auto focus motors in them

I'm not blaming that poster at all, but the statement highlights that not everyone understands what the "D" means.

Different explanation that is also possible: the OP called his own lens the "18-35mm Nikkor D lens" in the first post, and the poster you quoted could have simply reused that phrase to ask if the OP is absolutely certain about the type of his lens, knowing that there is a Nikkor AF 18-35 D and a Nikkor AF-S 18-35 (so likely with some knowledge about the Nikkor portfolio and presumably the meaning of 'D'). Since the OP claimed the lens had autofocus on the FTZ before he upgraded the firmware, it would have been possible that he had the AF-S lens instead and simply mixed up names.

Anyway, this will not lead anywhere further now, I'm afraid. I made my point, I'll keep using "AF D" and "AF-D" synonymously, certainly NOT with the intention to confuse anyone.

But even though it's not an 'official' abbreviation (but used by Nikon itself), for anyone shooting or familiar with older generation Nikkor lenses, 'AF-D' describes a screw-driven lens that provides distance information.

Not "anyone". I and others shoot older generation Nikkors and know perfectly well that AF-D does not mean external autofocus motor. I don't get it. It seems like you are advocating for perpetuating confusion and leaving people misinformed.

That's certainly not my intention, no.

I am honestly a bit surprised how that topic escalated

I have been living under the impression that 'AF-D' is used synonymously for 'AF D' lenses, explicitely not including AF-I or AF-S D lenses. That gives the following nomenclature for autofocus lenses that I, personally, and the few other Nikonians I know, all use and find completely logical:

  • AF (non-D)
  • AF-D
  • AF-I
  • AF-S
  • AF-P

The only thing that doesn't fit into this simplified naming scheme is the already mentioned AF DX 10.5/2.8 G Fisheye. Following that scheme, everything 'AF-D' is screw-driven.

But maybe I'm living in a Nikonian bubble that is not 'nitpicky' enough... even though I am typically accused of being just that

As Nikon themselves say, AF-D and D are the same thing. Some have focus motors and some don't. You can call that nitpicky if you want.

He's thinking that he got the specs mixed up with a newer version of this lens when he thought he was buying one that would autofocus with the FTZ. Now how my initial tests with it led me to believe that the autofocus was working (pre-update)... 🤷.

Nope. Not possible.

Seems like there's living/posting proof to the contrary? 😅

Well you are living proof that you believed focus to work, not disputing that, but if you really have the 18-35 D, then you believed wrong.
