G-type nikkor lens
EN: G-type nikkor lens
G-type NIKKOR lenses have no aperture control ring and are intended for use on Nikon D-SLRs that allow the lens aperture to be adjusted via the camera s command dial. In addition, like D-type NIKKORS, G-type optics relay subject-to-camera distance information to Nikon digital SLRs. The information is used to help determine ambient and flash exposure. A G-type lens will have the abbreviation G labeled on the lens barrel.
