This 77mm Neutral Density/Polarizer Filter from Light Craft is a multi-coated glass circular polarizer and neutral density (ND) filter that's thin enough to use on wide-angle lenses (as wide as 16mm in full-frame or 35mm format). It's designed to control exposure, permitting the use of high-speed film in bright sunlight and slow shutter speeds to enhance the appearance of motion. It reduces the amount of light reaching the sensor or film by 3 f/stops. By rotating the filter, the polarizing qualities of the filter can remove unwanted reflections from non-metallic surfaces such as water and glass, and can also provide more saturated colors.
