B+W 65-1065295 43mm Circular Polarizer Filter

The 43mm Circular Polarizer Filter (Single Coated) represents an innovative design in lens coating. Single coating is applied to one layer on each glass surface. This improves light transmission from about 92% (in uncoated glass) to about 98%. Single coating also has certain anti-reflective properties that help prevent against ghosting and internal flaring. You can also use this filter when shooting into glass or windows since it will, again, either increase or decrease reflections.
