The B+W 95mm Kaesemann High Transmission Circular Polarizer MRC Filter has the same pictorial effect as a linear polarizer, but it allows for correct exposure metering and autofocus distance settings. The filter includes Kaesemann polarizing foils that have a higher efficiency than conventional foils. These foils are cemented between plane-parallel optical glass, and then precision-polished to achieve a highly accurate plane-parallel surface. The foils are also sealed tight to protect against humidity. The filter includes an MRC-nano coating that reduces ghosting and reflections to maintain optimal levels of saturation and color tonality.
