A circular polarizer filter is a creative's most sought-after camera accessory as it helps bring contrast and vivid, natural saturation to both photos and video. Normally, a CP is used for landscape compositions featuring water, snow, ice, blue skies, and foliage as it can help darken the sky, remove reflections, and reduce unwanted glare from the scene. Custom-engineered to directly replace the front lens element on the HERO9/10/11/12 Black Cameras, each filter features CinemaSeries™ Glass with the durability and protection built to withstand impact and fast-paced environments. FEATURES Compatible with  Hero13® Black, Hero12® Black, HERO11® Black Mini, HERO10® Black, HERO10® Black Bones, and HERO9® Black cameras. Includes CP filter + protective hard case. Rotatable polarizing bezel with polarization indicator. CinemaSeries™ Glass - 16 coating layers reduce flaring and help protect against fingerprints, oils, and scratches.
