ARecognizing CPU and Type G, E, and D Lenses

CPU lenses (particularly types G, E, and D) are recommended, but note that IX-NIKKOR lenses can not be used. CPU lenses can be identified by the presence of CPU contacts, type G, E, and D lenses by a letter on the lens barrel. Type G and E lenses are not equipped with a lens aperture ring.

AAF-S/AF-I Teleconverters

If the combined aperture when the camera is used with an AF-S/AF-I teleconverter is slower than f/5.6 but is equal to or faster than f/8, autofocus and electronic

rangefinding will be available only with the center focus point and the camera may be unable to focus on dark or low-contrast subjects. Single point AF is used when 3D-tracking or auto-area AF is selected for AF-area mode (0 86). Autofocus is not available if teleconverters are used with the AF-S VR Micro-Nikkor 105mm f/2.8G IF-ED. If TC-17E II, TC-20E, TC-20E II, or TC-20E III teleconverters are used with the AF-S NIKKOR 300mm f/4E PF ED VR, autofocus is available only in AF-S mode.

ALens f-numberThe f-number given in lens names is the maximum aperture of the lens.
