The Canon EF/EF-S Lens to Canon EOS R Camera ND Filter Adapter allows you to pair any Canon EF or EF-S lens to the Canon EOS R or EOS RP mirrorless camera. It provides direct mechanical and electrical coupling between the lens and the camera. Incorporated into this adapter is a drop-in slot for an included 1.5-9 stop neutral density filter. It has a built-in filter rotation wheel for greater control over exposure. ND filters allow you to use slow shutter speeds even in bright daylight for silky smooth water/cloud effects and lighting experiments.
