Hoya HD CIR-POL 72mm filter with high transparency and UV durability, featuring a 25% larger absorption membrane than the standard polarizer. It has an HD coating with 8 layers of anti-reflective protection, and is resistant to water, oil, scratches, and stains.

Compatible with wide-angle lenses, the filter has a very thin HD frame where the glass is placed using high-pressure technology. It enhances color and contrast, allowing users to choose which rays of light enter the camera lens.

It removes unwanted reflections from non-metallic surfaces such as water and glass, while colors become more saturated with better contrast. It is often used to increase the contrast and saturation of blue skies and white clouds. Hoya polarizing filters do not affect the overall color balance.
