The JJC LMA-NK EOS(II) ultra thin lens mount adapter is made of black anodised aluminum (camera body mount) and brass silver (lens mount).
This adapter allows you to use the majority of Nikon F and AI (auto or manual focus) lenses on your Canon EOS camera, saving you the expense of a costly and irreversible conversion.
Since the adapter does not provide electrical contact translation, automatic diaphragm, auto-focusing, or any other functions will not operate correctly. In this case "stop-down mode" will need to be used when metering. The through-the-lens exposure metering function is supported.
\The Nikon lens has to be set to manual mode or aperture priority. Focusing can be infinity.
