Hoya 37mm EVO Antistatic Circular Polarizer Filter

The Hoya 37mm EVO Antistatic Circular Polarizer Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions. A circular polarizer differs from a linear polarizer in that it supports full use of a camera's autofocus and auto exposure functions.

The EVO antistatic coating on this filter helps to repel dust, as well as water, scratches, and stains, and aids in making the substrate easy to clean. Additionally, a 16-layer Super Multi-Coating helps to reduce surface reflections and ghosting for maintained contrast and clarity. The optical glass filter is set within a two-piece low-profile aluminum ring, which lessens the likelihood of vignetting if used on a wide-angle lens. The ring also features front threads for attaching additional filters or lens caps.
