The 67mm Neewer HD Variable ND Filter 67mm 3-7 Stopsis adjustable from 3 to 7 stops, with a rotating ring to reduce light intake and extend exposure time when shooting at slower shutter speeds and wider apertures. Perfect for capturing rivers, waterfalls, light trails, and other moving subjects with dynamic motion blur. Advanced cutting-edge technology allows you to say goodbye to the X-cross mark on images and other common problems that plague other variable ND filters for wide-angle and telephoto lenses. With double-sided and multilayered nano coatings, the minimum light reflection rate is less than 0.1%. This reduces glare and ghosting, blocks UV rays from 300 to 380nm, and ensures accurate color reproduction. The filter is water, oil, scratch, and dirt-proof.
