Designed for use with the Canon Variable ND Filter 1.5 to 9-Stop Drop-InDrop-In Filter Mount Adapter EF-EOS R, this Canon Variable ND Filter 1.5 to 9-Stop Drop-Inis an intuitive and sleek means for using a variable neutral density filter in conjunction with an adapted lens, especially those lenses lacking traditional filter threads. This variable ND filter is permanently installed within a drop-in holder and has an integrated wheel for adjusting the rotation position to alter the ND effect.

The variable ND filter provides 1.5 to 9 stops of adjustment and creates a darkening of the entire image for photographing with a wider aperture or slower shutter speed than normally required. The degree of density is easily controlled by rotating the filter, helping you to predetermine the additional exposure length required. By increasing your aperture or slowing your exposure time, you are able to control depth of field and convey movement more easily.

A: No, the Canon Mount Adapter EF-EOS R 0.71x (seen here: https://bhpho.to/3OmrCw5) does not accept the Canon Drop-in Variable ND Filter A.

Q: 6. Why is it MORE expensive to buy just the filter without the adapter included?

A: While Canon sets the MSRP on their items, as of the time/date of this reply, the cost of the Canon Drop-In Variable ND Filter A (1.5-9 Stop), BH #CADIVNDFA, and the Canon Drop-In Filter Mount Adapter EF-EOS R with Variable ND Filter, BH #CAMAEFRFDIND, on our website are currently the same price. However, I would simply recommend that if you are certain that you want the Variable ND Filter, as it is the most expensive of the filter options that are compatible for use with the Canon Drop-In Filter Mount Adapter EF-EOS R, I would simply recommend to purchase the adapter kit that comes with the Variable ND filter, the Canon Drop-In Filter Mount Adapter EF-EOS R with Variable ND Filter, BH #CAMAEFRFDIND.

Q: 7. Would this filter cause a colour shift when combined with the Hoya UV and IR Cut filter?

A: The Hoya 72mm Variable Density II Filter is meant to be color neutral without any color shift. This should not cause a color shift even if used with the Hoya 72mm UV and IR Cut Filter. One thing to keep watch for is an X-pattern near the maximum density.

Q: 8. How big is the actual filter? Will this drop in to the 52 mm filter slots at the back of Canon telephoto lenses?

A: I don't have the actual dimensions but the filter is permanently mounted in the holder and it will only fit into the canon drop in filter mount adapter. See BH #CAMAEFRFDIND.

Q: 9. Does this filter have click stops for each ND stop? If so, do the click stops work even when the set screw/knob is removed?

A: No, the filter has no stopping when changing the filter strength. It is smooth throughout, with no hard stop.

Q: 10. Is there a non-variable ND drop in filter for this mount? Like a set of multiple NDs? I can't stand the color shift and increased contrast variable NDs create. I'd much prefer to just carry around a few drop in's at varying ND levels

A: We're afraid not. At this time Canon does not offer any alternative ND Filters for this system.
