D mount lens.
Thought Nikon was F mount.
I seen D mounts. What is the story?
Thanks
Where did you see the D mount?
Nikon Nikkor 28-80mm f/3.3-5.6 Nikon AF-D mount lens
The "D" stands for distance. It indicates that the lens transmits distance information to the camera. It is still an "F" mount.

There is a Nikon F mount that goes back a half century+. Still in use today. You may be confused with the Nikon lenses that were called D lenses.
D lenses will not auto focus on D3000x and D5000x Nikon cameras. These cameras lack a focusing motor. FYI

Nikon is F mount. But they have D lenses and E lenses and G lenses and S lenses. Has nothing to do with the mount.

From the Nikon glossery:
D-Type NIKKOR Lens
A NIKKOR lens that sends distance information to the microcomputer of a dedicated Nikon camera. D-type lenses can be distinguished by a model name in which the letter D follows the maximum f/number.

The is an F mount lens. The correct nomenclature for this lens is AF 28-80mm f.3.3~5.6D. The AF = auto focus and the D denotes that distance information is communicated through the camera to a compatible speed light (flash unit) for setting the correct flash duration based on the distance from the photographer to the subject.
Nikon has the F mount but they use D to indicate the camera will communicative with the flash during a flash exposure for distance.
I believe that distance, without using flash, is also recognized by the camera with the D lenses.

Absolutely incorrect!
"D" has nothing to do with the focus drive, it only designates that the lens has a focus confirmation chip in it that transmits focus data to the cameras PCB.
What determines if a lens will AF on the entry level Nikon bodies you note is the focus drive system of the lens. "AF" designated lenses have the older mechanical screw drive focus motors and will NOT AF on those entry level bodies.
AF-I, AF-S, & AF-P designated lenses have electronic focus motors inside the lens and wil auto focus on any current series Nikon DSLR.
There are several Nikon lenses that carry BOTH the AF-I or AF-S AND "D" designations and will AF on those entry level lenses. I personally own 3 of them. The AF-S 17-35MM F2.8D, AF-S 28-70MM F2.8D, & AF-I 400MM F2.8D.
ALL Nikon SLR & DSLR lenses are made wth the Nikon "F" mount except the very short lived Pronea series cameras.

There actually is a 'D-mount' .... also a 'C-mount'. Both were generic mounts used by small movie cameras. I believe the 'D-mount' was slightly smaller. The 'C-mount' has been used by security systems, with Canon and Pentax providing new lenses for them. I have a few of each mount - I believe the lens below is 'C-mount', but I'm not positive.
