The KIWIFOTOS LMA-NK_EOS(II) ultra thin lens mount adapter is made of a black anodised aluminium (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.
