Product Features
Designed for use with the Canon Drop-In Filter Mount Adapter EF-EOS R, this Drop-In Variable Neutral Density Filter A is 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 creates a darkening of the entire image, allowing you to photograph 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 slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily.
