Hoya HD MkII CIR-PL 52mm cirkulárny polarizačný filter

The Hoya HD MkII CIR-PL 52mm is a premium circular polarizer filter designed for photographers and videographers who demand superior image quality and durability. Part of Hoya's renowned HD MkII series, this filter features chemically hardened optical glass that is 4x stronger than conventional glass, ensuring long-lasting performance in demanding conditions. The 16-layer multi-coating (8 per side) provides anti-reflection, water-repellent, oil-repellent, scratch-resistant, and anti-static properties, making it easy to clean and maintain. With a slim, lightweight aluminum frame, the filter minimizes vignetting even on wide-angle lenses. It effectively reduces reflections from non-metallic surfaces, enhances color saturation and contrast, and darkens blue skies for dramatic landscape shots. The filter factor ranges from 2.5x to 5x (approximately +1.3 to 2.3 stops), allowing for creative control over exposure. Front filter threads enable stacking with other filters. Ideal for outdoor, travel, and nature photography, this filter is a must-have for any serious photographer.
