The 43mm HD Variable ND Filter from Neeweris 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. The rotation range is limited to approximately 70°, and advanced cutting-edge technology lets you say goodbye to the X-cross mark on images and other common problems with variable ND filters for wide-angle and telephoto lenses. With 30 layers of nano coating, the minimum light reflection rate is less than 0.1%, which reduces glare and ghosting, and blocks UV rays from 300 to 380nm, while ensuring accurate color reproduction.
