Circular Polarizer (CPL) Compatible with Canon EF 24mm f/1.4L II USM

Circular polarizing (CPL) filter made for the Canon EF 24mm f/1.4L II USM that reduces unwanted reflections from non-metallic surfaces such as water and glass while boosting color contrast and saturation. By selectively filtering directionally polarized light at right angles to reflections, the CPL absorbs much of the reflected light—clearing haze in distant landscapes and producing richer, more vivid blues and brighter white clouds. The filter delivers its strongest effect when used at a 90° angle from the sun. Built with an ultra-slim aluminum frame to prevent vignetting yet retain rotational movement for precise adjustment. A nonslip upper rim makes the filter easy to mount, rotate and remove. Optical surfaces feature double-sided, multi-layered coatings that are anti-oil, anti-dust, anti-soil, scratch & water resistant.
