Circular Polarizing Filter (CPL) for Canon RF 15-35mm F2.8 L IS USM — Ultra-Slim Aluminum Frame

Ultra-slim aluminum frame reduces the risk of vignetting while still allowing full rotation to fine-tune polarization. A nonslip upper rim makes installation, rotation and removal quick and secure. The filter glass features double sided, multi-layered coatings that are anti-oil, anti-dust, anti-soil, scratch & water resistant. As a circular CPL, it eliminates unwanted reflections from non-metallic surfaces like water and glass and enhances overall color and contrast. Frequently used to deepen blues and increase the saturation of white clouds, the filter arranges and filters directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light. This clears distant haze and produces more saturated, vivid colors; the effect is strongest when the filter is used at a 90° angle from the sun.
