This Kolari Vision kit includes the EF-EOS R Drop-In Lens Adapter and a VND Drop-In Filter. The adapter is compatible with the Canon EOS R, R5, R6, and RP. It attaches to the RF mount of the camera and allows you to attach EF-mount lenses, as well as install various filters from Kolari, like the included VND filter. It also supports Canon filters designed for their own EF-EOS R Drop-In Adapter. (The included VND filter is likewise compatible with the Canon adapter.) Please note that the Kolari adapter only functions properly when a filter is inserted.
The drop-in adapter was carefully designed to provide precise register distance for optimal focus and sharpness when using your lenses with drop-in filters. The lightly baffled interior helps reduce stray reflections, and the exterior offers an effective weather seal against the lens and drop-in filters. The adapter features an aluminum shell with a rugged, knurled traction grip.
The VND Drop-In Filter is a 2- to 10-stop variable ND filter. It provides a smooth, clickless transition between 2, 3, 4, 5, 6, 7, 8, 9, and 10 stops. The frame is aluminum and the optics are glass with AR/AS coatings for increased transmission, reduced reflections, and easy cleaning. The filter has a wide grip and offers a lanyard attachment point for your convenience. Also, it's thickness-matched to minimize focus shift.
When the VND filter is used with certain ultra-wide lenses, you may see a color cast or X effect at 8, 9, and 10 stops.
