Quick Overview

The D|Focus Polarizer is a circular polarizer, so it’s compatible with all digital sensors. We sourced our polarizers from a boutique optics company in the UK. The filters are made from Schott Superwite glass - the world’s best optical glass material. Schott Superwite has the highest contrast and the lowest index of refraction of any optical material on the market. The filters are skillfully lapped and polished on advanced, computer controlled manufacturing machines to create an ultra-flat optical surface free of aberrations. Rest assured that the D|Focus polarizer competes head-to-head with the best polarizing filters on the market.
