SmallRig 4225 CINE 4 x 5.65″ ND0.9（3 Stop）Filter

SmallRig 4 x 5.65″ ND0.9（3 Stops）Filter 4225 is one of the CINE ND filters designed for professional photographers. It features 12.5% light transmittance, with three 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 multi-layer 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.
