D. Lenses with this designation convey distance information to the camera to aid in metering for exposure and flash.

G. These are lenses that lack a manually adjustable aperture ring, so you must set the aperture on the camera body. Like D lenses, G lenses also convey distance information to the camera. Most current Nikon lenses in production are G lenses.

AF, AF-D, AF-I, and AF-S. All of these codes denote that the lens is an autofocus (AF) lens. The AF-D code represents a distance encoder for distance information; AF-I indicates an internal focusing motor; and AF-S represents an internal Silent Wave Motor.

DX. This code lets you know that the lens is optimized for use with the Nikon DX-format sensor. NOTE Full-frame lenses do not carry an FX designation, and you can use them effectively on DX cameras albeit with a smaller angle of view than on an FX camera.
