- SH-PMC broadband coatings of 8 layers per side for the higest reflection reduction (below 0.2%)
- Dust and moisture repellent top coating on each side for easy cleaning and longest life
- Constructed from Schott glass for optical clarity
- Brass filter ring helps to prevent jamming and provides additional strength
Overview
The Heliopan 40.5mm Slim 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.
