4×5.6 Circular Polarizer

Description

The Cavision 4 x 5.65″ 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 measures 4 x 5.65″ / 101.6 x 143.5mm and is constructed from 4mm-thick optical glass.
