Hoya HD3 Circular HRT Polarizer Filter (52mm)

The HD3 Circular HRT Polarizer Filter from Hoya reduces reflections and glare by filtering out light that has become polarized due to reflections from a non-metallic surface to provide an increase in the saturation of skies and foliage. This filter utilizes optical thin HRT (high rate transmission) polarizing film that yields super-sharp, high resolution images to meet the demands of 100MP+ camera sensors. Eight layers of anti-reflection nano coatings on each side of the filter provide over 92% light transmission. This ultra-hard nano coating technology produces scratch- and stain-resistant HMC multicoating. The nano coating results in an improved beading effect when in contact with water or oil and helps keep the filter clean for longer than uncoated filters.
