Circular Polarizing (CPL) Filter — Compatible With Sony E 30mm F3.5 Macro

This circular CPL filter removes unwanted reflections from non-metallic surfaces like water and glass while boosting color depth and contrast. It is especially effective for intensifying blues in skies and enhancing the appearance of white clouds, clearing haze in distant landscapes and producing richer, more vivid colors. The filter delivers its strongest polarization effect when positioned at a 90° angle to the sun. Built with an ultra-slim aluminum frame to prevent vignetting, the filter still allows full rotation for level adjustment. A nonslip upper rim makes installation, rotation and removal quick and secure. The glass features double-sided, multi-layered coatings and is anti-oil, anti-dust, anti-soil, scratch & water resistant. CPL filters work by arranging and filtering directionally polarized light perpendicular to reflected light, allowing much of that light to be absorbed and reducing glare.
