The Kiwifotos Nikon G Mount Lens to Sony NEX Camera Adapter allows you to mount a Nikon F lens onto a Sony NEX camera body. The all-metal adapter is designed to fit the lens securely, yet can still be removed easily when not needed. Autofocus, automatic aperture and AE metering will be disabled by the lens adapter as there will be no electrical communication between camera body and lens. You will need to focus manually, and to set exposures manually or meter in aperture priority mode. The lens will retain its ability to focus to infinity.
