The 3-stop, 67mm Edge ND Filter from IRIX is an essential tool for landscape and long-exposure photography. This filter has an optical density of 0.9 and reduces incoming light by 3 stops, allowing more controlled motion blur and depth of field manipulation.

This optical glass filter features waterproof and oil-repellent nanocoating to prevent stains and fingerprints, allowing it to be used in extreme weather conditions. The low-profile frames and knurled edges provide excellent grip and functionality with a reduced potential for vignetting with wide-angle lenses.
