The Polaroid 55mm 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.
This filter is constructed from optical glass and features an aluminum filter ring to provide increased rigidity and as well as resistance against expansion or contraction due to temperature variances.
