Circular Polarizing CPL Filter for Sony FE 85mm F1.4 GM — Ultra-Slim Aluminum Frame

Designed to cut reflections from non-metallic surfaces (water, glass, etc.), this circular polarizer (CPL) also boosts color saturation and contrast — especially effective for deep blue skies and bright white clouds. Optical action: the CPL arranges and filters directionally polarized light perpendicular to reflected rays, absorbing much of the unwanted glare, reducing haze in distant landscapes and producing more vivid, saturated colors. Mechanical design features an ultra-slim aluminum frame to prevent vignetting while retaining full rotation for polarization adjustments; a nonslip upper rim makes mounting, turning and removal simple. Optics are protected by double-sided, multi-layered coatings that are anti-oil, anti-dust, anti-soil and resistant to scratches and water.
