Circular Polarizing (CPL) Filter — Compatible with Canon RF 24-105mm F4-7.1 IS STM

Engineered with an ultra-slim aluminum frame to prevent vignetting while preserving full rotational movement for adjusting levels. A nonslip upper rim aids quick, secure installation, rotation and removal. Optical surfaces feature double-sided, multi-layered coatings and are anti-oil, anti-dust, anti-soil, and scratch & water resistant. As a circular CPL, this filter removes unwanted reflections from non-metallic surfaces such as water and glass and enhances color and contrast — notably increasing saturation and contrast in blue skies and white clouds. It works by arranging and filtering directionally polarized light perpendicular to the reflected light, allowing absorption of much of the glare, clearing haze in distant landscapes and producing more saturated, vivid colors. The effect is strongest when used at a 90° angle from the sun.
