B+W 40.5mm Kaesemann High Transmission Circular Polarizer MRC Filter

Overview

The B+W 40.5mm Kaesemann High Transmission Circular Polarizer MRC Filter provides the same pictorial effect as linear polarizers, but it provides better exposure metering and autofocus distance settings. The filter is equipped with Kaesemann polarizing foils, which are placed between plano-parallel optical glass surfaces. The resulting sandwich is then precision-polished to ensure an accurate plano-parallel surface. Each glass surface layer of the filter has anti-reflective coating to prevent internal ghosting and maintain optical fidelity and color tonality. The filter also includes a multi-resistant coating to protect against dust and humidity. To prevent jamming and increase durability, the filter has an F-Pro brass ring design which does not bind to the aluminum housing of the lens.
