The Kiwi Photo LMA-NK (G) EOS ultra-thin lens mount adapter provides the ability to use the majority of Nikon F and AI (auto or manual focus) on Canon EOS camera bodies. The Adapter is made of black anodized aluminum with a brass chrome ring. Although the lens can be physically attached to the body, functions such as automatic aperture, auto-focus and / or other functions will not work. You can then take pictures in manual mode. The adapter is also equipped with an "ON / OFF" aperture ring for the user to control the use of aperture . Focus to infinity is available.
