This Benro Aureolo Circular Polarizer Filter reduces glare from naturally reflective surfaces, making it ideal for shooting outdoors in daylight. When filming or photographing water or snow, the light reflection has the ability to overexpose or degrade your image quality. The multicoated optical glass mitigates this issue and darkens the sky while offering scratch and water resistance. Colors become more vibrant and saturated as a result. The filter's slim design reduces vignetting and keeps its profile compact.
