I was referring to AF-D lenses not f/4 D lenses.

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.

AF-D and D are the same thing. From Nikon's web site:

AF-D
Nikon introduced AF-D series lenses in 1996, while these lenses look similar to AF lenses they contained an encoding microchip that transmits focusing distance information to the camera body, this information is used to enhance the accuracy of the cameras exposure and flash metering systems. Cameras with advanced 3D matrix metering systems require AF-D compatible lenses to take full advantage of this technology. All current Nikon autofocus lenses transmit distance information to compatible cameras and are therefore AF-D compatible, AF-D lenses are recognised by the D designation marked on the lens as illustrated in the image below.
