The 77mm Screw-In CPL III Filter from Kase is a screw-in circular polarizer that reduces reflections and enhances saturation and contrast when shooting blue skies, clouds, water, snow, plants, and more. The filter is also effective when shooting high-resolution photo and video of scenes with fine detail. Featuring B270 optical glass, the filter's low reflection rating of less than .1% means more light transmission and better control of ghosting and flare. A new coating promotes clarity when working with telephoto lenses, while the glass surface is more durable and scratch-resistant. The filter is also waterproof, oil-proof, and anti-mildew to protect the front lens element during use in adverse weather conditions.
