SmallRig 4 x 5.65″ ND2.1 (7 Stops) Filter 4228 is one of the CINE ND filters designed for professional photographers. It features 0.78% light transmittance, with seven stops of light extinction, and optical glass, precisely ground and polished for use with a 4 x 5.65″ filter tray or matte box. Made of high-clarity, high-transmission B270 optical glass from Germany, this filter is coated on both sides with multilayer nano-coating to ensure high-accuracy color reproduction. These coatings are mildew-proof, waterproof, oil-resistant, and anti-scratch, making the item easy to clean and store, and ideal for use in video or film shooting. The filter allows for a wider aperture for added blur of the background and control of image sharpness, thereby improving latitude and image quality.
