The “D” designation was added to the autofocus AF lenses when Nikon upgraded the electronics to communicate focus distance to a compatible speedlight for more precise exposure control.

The distance information is used for more than just flash - it's well explained in the “Nikon Compendium” and Braczko's “The Complete Nikon System.”

It has nothing to do with the focus mechanism.

Right, That's what I've been saying all along.

I understand that the D on the lens refers to the distance being listed on the lens when focusing, to get an approximate focus distance.
I don't want a G (gelded)lens but a lens that I can pick the aperture on the lens and not through the camera. I am very happy to do everything manually.
Received good information, so thanks.

The camera uses the distance information from the lens for exposure purposes only.
