This ultra thin lens mount adapter is fine finishing and made of black anodized 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.
Since the adapter is manual, 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. Preserve all focusing range up to the infinity point.
