Hoya 52mm Warm Circular Polarizer Filter

After a unique collaboration between Hoya and esteemed wildlife photographer and conservationist B. Moose Peterson of Wildlife Research Photography, the 52mm Warm Circular Polarizer Glass Filter was born. This high-quality filter ingeniously combines the functionality of a polarizer with the warming effects of an 81A filter. For decades, photographers have relied on polarizers to eliminate reflections from non-metallic surfaces such as water and glass. They are also instrumental in darkening blue skies to enhance contrast in landscape photography. However, using traditional linear polarizers with today's auto-focus cameras, which often employ a split beam metering system, can lead to exposure errors due to their light absorption properties. This is where our durable and effective circular polarizer filter comes into play. It delivers the same optical effect as a linear polarizer, but without causing exposure issues with modern metering systems.
