Featuring a unique 15-layer multi-coated design, the Formatt-Hitech 77mm Firecrest SuperSlim Circular Polarizer Filter helps to reduce reflections and glare as well as increase the overall saturation of an image. This unique polarizer filter is characterized by the advanced Firecrest coating, which offers full attenuation of UV light for increased clarity and contrast, as well as a marked reduction in surface reflections and protection against scratching.

A polarizing 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 SuperSlim aluminum alloy filter ring measures 7.5mm-thick and its slim design helps to minimize the likelihood of vignetting. This filter features front threads for stacking additional filters or attaching a lens cap.
