Canon EF-EOS R adapter (with V-ND filter)

The EF-EOS R lens adapter for drop-in filters offers the same functionality as the EF-EOS R lens adapter, but with the added capability of attaching drop-in filters. This means that the filter no longer needs to be mounted at the front of the lens, which is particularly advantageous when using wide-angle lenses with a large front element. It includes a neutral density filter (drop-in filter). Neutral density filters help control the amount of light entering the camera. This is especially useful for filmmakers who want to shoot in bright environments with a combination of wide aperture and long exposure times. Additionally, landscape photographers can use it to achieve longer exposure times, creating a blur effect for the movement of clouds in the sky and on the water's surface.
