The 40.5mm Neewer ND Filter is designed to reduce the light entering the camera by 10 stops. It's ideal for slowing shutter speeds to create a smooth look with flowing water or to use wider apertures in bright light to blur the background. The optical glass is waterproof and has an anti-scratch surface. The filter features multiple layers of nano coatings on both sides.
