Circular Polarizer (CPL) — Compatible with Sony DT 30mm F2.8 Macro SAM

Designed for the Sony DT 30mm F2.8 Macro SAM, this circular polarizing (CPL) filter reduces unwanted reflections from non-metallic surfaces such as water and glass while intensifying color and contrast. By arranging and filtering directionally polarized light perpendicular to reflected light, the filter can absorb a large portion of glare, cut haze in distant landscapes, and deliver richer, more vivid colors — with the strongest effect when positioned at a 90° angle to the sun. Construction and handling: an ultra-slim aluminum frame minimizes the risk of vignetting while still allowing smooth rotation for precise adjustment. A nonslip upper rim makes the filter easy to mount, rotate and remove. Optical protection: the glass features double-sided, multi-layered coatings and is anti-oil, anti-dust, anti-soil, scratch & water resistant for improved durability and easier cleaning.
