This 4 x 5.65" Neutral Density 0.6 Filter from SmallRig reduces exposures by 2 f-stops, making it possible to reduce shutter speed for added blur, or reduce aperture to reduce depth of field for help isolate the image subject. This filter is compatible with any 4 x 5.65" matte box or filter holder that has a filter slot for 4mm-thick filters.
Made with high-clarity, high-transmission B270 optical glass, this filter is precisely ground and polished for use with lenses of various focal lengths without compromising image sharpness. The filter is coated on both sides with multilayer nano-coating to reduce lens flare and optimize light transmission. The coatings are also mildewproof and water resistant, toughened to prevent stains, and easy to clean, making the filter ideal for use in harsh environments.
