Probably watching the show in disbelief (the original question has been answered though).

Have I missed anything?

Not a lot: AF-P lenses also exist with E-type aperture (e.g. the 70-300 FX zoom).

Yes, thank you, I have corrected it my previous posting.

Come to think of it, the Z 58 f/0.95 doesn't  autofocus at all, but surely it also communicates distance info to the camera.  As you say, D functionality is not about focus control.

You are right, but these old designations like D,G,E,etc. may be obsolete now in the Z mount...

There are also the perspective control (PC) lenses that are D and E-type manual focus lenses. But that's only of peripheral interest here.

If there are AF-D lenses that have internal motors, I guess I have come across any yet.

I guess I assumed the op was talking about an AF-D lens. My bad.

What you have discovered is that the AF-D nomenclature is misleading. The 300/4 D is just as much a D lens as all the other D lenses, and there is more than a dozen D lenses that do have internal AF motors. The relevant categories are AF, AF-I, AF-S, AF-P, not "D or not D".

Is there a list of the D designation lenses with internal motors somewhere ?

Anyway the original posters' lens does not appear to be one of them, does it ?

Hi,

And a couple AI-S manual focus lenses with the D chip in them. But they are labelled AI-P rather than AI-S....D. I think they were trying to avoid more D confusion.

Indeed, Ai-P is a thing, but hopefully, nobody expects AF from those.

If it says AF-S or AF-I on them, they have a motor.

No. It isn't, meaning this lens never focused on that camera, even before the firmware update.

Re: FTZ adapter firmware update broke autofocus on 18-35mm D?

Hi,

Hey! Now that you mention it....My AI-P 500/4 doesn't auto focus!

I never did get the AI-P variant of the 45/2.8 although I did think about it a few times. I have the original GN version and went back to using it on the Df. That's a Pre AI lens and so needs the flip up AI tab on the Df. Ought to work on a Z though.

And now that brings up more Nikon Alphabet Soup. Pre-AI isn't an official designation. The GN is a Type-K rather than a Type-A... But maybe we should leave the remaining Alphabet Soup alone....

And, for those unfamiliar, the GN means Guide Number. It's a special design for use with flash bulbs and early electronic strobes. It has a Guide Number ring that you set for your flash. It then couples the focusing and aperture rings. As you focus closer, the aperture stops down. And it opens up as you focus further away. Works amazingly well.

Nikon revisited the lens minus the GN for the FM3a and added the distance chip and encoder strip making it an AI-P lens.

Hi,

From OP's gear list , it is this lens ( without internal focus motor ! ) : Nikon AF Nikkor 18-35mm f/3.5-4.5D IF ED Specs: Digital Photography Review (dpreview.com)

There is another 18-35 mm lens with internal focus motor : Nikon AF-S Nikkor 18-35mm f/3.5-4.5G ED Specs: Digital Photography Review (dpreview.com)

If OP is correct that his lens did autofocus before the firmware update of the FT adapter , it is the AF-S 18-35 mm lens.

Since the AF-D discussion has started again, here is a useful resource:

http://www.photosynthesis.co.nz/nikon/lenstype.html

  • AF - Auto focus (1986)
  • Lens focused by motor in camera, 5 CPU contacts on lens mount.
  • D lens (1992) - Transmits focus Distance for improved flash metering.
  • AF-I (1992) - Telephoto with Integrated AF motor, 10 CPU contacts, manual override of AF.
  • AF-S (1996) - Similar to AF-I with improved Silent Wave motor.

Ha, oops. Didn't realize I was stirring up some well-trod territory! Thanks for the resource.

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)... 🤷.

Interesting. I was not aware of any of them, most likely because  I entered the Nikon world not before 2006 (with a D80 at that time). Reading quickly some reviews of the first four lenses in the list, they don't seem to be Nikon's best performers...

Yes, this is funny. Maybe the large depth of field at 18 mm helped to get the impression that the AF worked as expected...
