The 43mm Neewer HD Variable ND Filter 43mm 3-7 Stopfrom Neeweris adjustable from 3 to 7 stops, with a rotating ring to reduce light intake and extend exposure time when shooting at slower shutter speeds and wider apertures. Perfect for capturing rivers, waterfalls, light trails, and other moving subjects with dynamic motion blur. The rotation range is limited to approximately 70°, and advanced cutting-edge technology lets you say goodbye to the X-cross mark on images and other common problems with variable ND filters for wide-angle and telephoto lenses. With 30 layers of nano coating, the minimum light reflection rate is less than 0.1%, which reduces glare and ghosting, and blocks UV rays from 300 to 380nm, while ensuring accurate color reproduction.

Q: 1. How many stops is the filter range?

A: The filter's wheel will cut light from 1 to 9 stops, or an optical density of .3 to 2.7. It is not know at this time (11/20/2018) if this filter will also work in lenses that have a similar drop in filter such as the 200-400/4/1.4x lens. An answer to this should be available in January.

A: Yes, the Meike Drop-In Filter Mount Adapter EF to EOS-R with Variable ND Filter is compatible with RED DIGITAL CINEMA KOMODO-X 6K Digital Cinema Camera (Canon RF) when used with EF lenses.

Q: 6. Do they make something like this that doesn't change the lens mount? Basically RF to RF, but allows me to have VND behind lens

A: No, lens adapters are made to connect different mounts. Unfortunately there are no adapters to just enable back VND filters on your RF cameras with their native lenses. Other brands make snap ND filters for the Canon RF camera mount, however they are fixed stops.

A: No.

Q: 8. Will this work on a Komodo?

A: While Canon does not list compatibility of the Canon Drop-In Filter Mount Adapter EF-EOS R with Variable ND Filter with the RED DIGITAL CINEMA KOMODO 6K Digital Cinema Camera (Canon RF), as the camera uses the Canon RF lens mount, yes, the adapter should be compatible for usage on the Komodo 6K Digital Cinema Camera.

A: No. This adapter does not change the crop factor.
