This Kolari Vision kit includes the EF-EOS R Drop-In Lens Adapter and VND, CPL & Clear Drop-In Filters. 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 and install a compatible drop-in filter from Kolari. It also supports Canon filters that are designed for their own EF-EOS R Drop-In Adapter. (The included filters are likewise compatible with the Canon adapter.) Please note, 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 light 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 offering smooth, clickless transition between 2, 3, 4, 5, 6, 7, 8, 9, and 10 stops. All three included filters feature an aluminum frame and glass optics with AR/AS coatings for increased transmission, reduced reflections, and easy cleaning. The filters have a wide grip and offer a lanyard attachment point for your convenience. They're thickness-matched to minimize focus shift.

Q: 8. Can I change lenses on the adapter without removing the adapter from the camera? I know the directions say to remove the adapter from the camera first, but I would like to know why.

A: Yes, Canon Drop-In Filter Mount Adapter EF-EOS R with Circular Polarizer Filter has a lens release switch to remove or interchange lens on the Canon full-frame mirrorless cameras. Canon recommends removing the lens and adaptor in the first step as a safety precaution. Also is assume that you are removing the lens to put your camera away instead of switching lenses in the field. There is no harm caused to the camera or adaptor if you keep the adaptor on the camera and remove just the lens.

Q: 9. I am more concerning the image quality and autofocus speed when using polarizer filter. Does it degrade the image quality of the captured image? Does it slow down the autofocus speed at all?

A: It works well , does not change the auto focus speed and does not degrade the image quality
