This 6 to 9-stop, 52mm Moment Variable ND Filter is designed to mount onto lenses with 52mm front filter threads. Its 1.8 to 2.7 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally possible. The degree of density is easily controlled by rotating the front filter ring, helping you to predetermine the additional exposure length required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. For easier, repeatable control over density settings, the front ring is visually demarcated with lines representing the different stop values and features side knurlings to further enable fast and precise positioning. To help ensure consistent exposures, the front ring is designed to prevent any rotation beyond the stop values etched on it.

This filter is constructed from Schott B270 glass for enhanced clarity and color fidelity. To prevent internal ghosting and reflections, while further enhancing clarity and color fidelity, each glass surface includes 15 layers of antireflection coatings. The filter is also coated for resistance to oil, static, and scratches, offering greater protection to the filter and helping it stay clean for longer than with uncoated filters.

Variable neutral density filter allows you to apply differing amounts of density from scene to scene.

1.8 to 2.7 neutral density filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally possible.

Providing a reduction of 6 to 9 stops, this filter allows you to control depth of field and convey movement more easily.

This filter allows for increased flexibility to use specific ISO settings or ISO films under bright ambient light.

Filter provides increased exposure flexibility while using cinema or video cameras within a designated film frame rate.

Filter is constructed from Schott B270 glass for increased optical clarity as well as color fidelity.

15 layers of coatings on each glass surface prevent internal ghosting and reflections.

Filter is coated for oil, static, and scratch resistance.

Aluminum alloy filter ring assembly offers durability while remaining lightweight.

Side knurlings provide a more textured grip during mounting or removal.

Front filter ring is constructed to help ensure that its rotation corresponds to the filter's exposure reduction range.

Microfiber filter cloth included for filter maintenance along with a metal filter case for storage and transport.

Related Questions and Answers

Q: 1. Will the IS on EF lenses work with this adaptor?

A: As the Meike Drop-In Filter Mount Adapter EF to EOS-R with Variable ND Filter does have electronic contacts to maintain electronic communication between the camera and lens, it should still maintain autofocus and image stabilization communication capabilities when used with Canon EOS R-series mirrorless digital cameras.

Q: 2. Is there a way to secure the adapter when using larger (cinema) lenses?

A: While the Meike Drop-In Filter Mount Adapter EF to EOS-R with Variable ND Filter could not be secured, you would have to secure the lens itself.

Q: 3. Does this speedboost the lens or its a regular adapter?

A: The Canon Drop-In Filter Mount Adapter EF-EOS R with Variable ND Filter is not a speed booster adapter.

Q: 4. Does this work with full frame camera and lenses?

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

Q: 5. Will this help dissipate heat for the Canon R5?

A: No.

Q: 6. Does the VND filter have any polarizing effects on the light entering the camera?

A: There have been no reports of a polarizing effect with this variable ND filter installed into the adapter.

Q: 7. Does this VND cause the "x"?

A: None that we can see. The ND stopped all the way down looks great with no X over the video.

Q: 8. Does this work on the RP as well?

A: Yes, the Meike Drop-In Filter Mount Adapter EF to EOS-R with Variable ND Filter would be compatible for use on the Canon EOS RP Mirrorless Camera.

Q: 9. Are there any astrophotography filters that fir this filter system?

A: I'm sorry, no.

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.
