Related Questions and Answers

Q: 1. 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.

Q: 2. Does this work with full frame camera and lenses?

A: Yes, this is for the EOS R system.

Q: 3. Is this compatible with Komodo X?

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: 4. The idea of a rear drop in filter holder is excellent. If you are using native R lenses, will there be a way to use a drop in rear filter feature? Funny that this feature would only apply to legacy glass.

A: No there is no option for that.

Q: 5. Does this include, or even support, the tripod "foot" (that comes with the $164 version, but not the $99 version)?

A: No.

Q: 6. Can this EF-RF adapter accept the Canon Super Telephoto drop-in filter holders?

A: Canon Drop-In Filter Mount Adapter EF-EOS R with Variable ND Filter has a built-in/ non removable Nd filter. There are no threads either to screw additional filters. The drop in filter magazine is also smaller than the standard telephoto drop in filter. It's dimensions are 6mm x 53mm x64mm.

Q: 7. Is this compatible with RF lenses? If not has Canon mentioned if there will be an adapter for RF lenses on the R? And if not are there alternatives?

A: This is only for EF lenses. I am not aware of any alternatives.

Q: 8. Will it also fit an original Canon 14 mm lens?

A: Yes, the following adapter will accommodate a Canon EF 14mm f/2.8L II USM lens.

Q: 9. can you use third-party filters like breakthrough photography filters in this adapter?

A: The Meike Drop-In Filter Mount Adapter EF to EOS-R with Variable ND Filter is a lens adapter that includes a Drop-In Variable ND Filter (ND3-ND500) and clear drop in filter. It is not designed to hold any other filter.

Q: 10. 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.
