Canon Drop-In Variable ND Filter A

A drop-in variable neutral density filter to reduce the amount of light entering the camera - ND effect can be adjusted from ND 2.5 to ND 500 equivalent* - great for filmmakers wanting to shoot at large apertures and landscape photographers shooting at long shutter speeds. This filter fits with the Filter Mount Adapter, which lets you connect your EF or EF-S lens to the EOS R system.
