A professional, world-class ND filter with 3-stops of light reduction, that provides a clear sharp image and is easy to use.
This ProMaster HGX Prime IRND filter mounts to lenses with 77mm threads and provides an exposure reduction of 3-stops (ND8 equivalent). It darkens the entire image allowing for slower shutter speeds and/or wider apertures with applications for both still photography and videography.
As an HGX Prime filter this solid ND is one of the finest in the world. Its Repellamax II coatings, optical glass, and color-corrected polarizing films (applied using a unique, super-secret, process) combine to provide an extremely sharp image with excellent color rendition as well as protection against moisture, oil, dirt, and dust. An incredible 36 layers of coatings are used in manufacturing this filter to a new, world-class standard!
