The Heliopan 46mm Circular Polarizer SH-PMC 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 SH-PMC multi-coating provides a total of 16 coatings, 8 per side, for significant reflection reduction (below 0.2%) as well as dust and moisture repellence for easier cleaning.
This Heliopan filter is constructed from Schott glass for increased optical clarity and color fidelity. It features a brass filter ring for durability as well as jamming prevention.
