Hoya UX CIR-PL (PHL) 37mm Circular Polarizer Filter

The Hoya UX CIR-PL (PHL) 37mm is a high-quality circular polarizer filter designed to reduce reflections from non-metallic surfaces such as water and glass, while enhancing color saturation and contrast. Part of the Hoya UX series, this filter features a slim, low-profile aluminum frame and multi-layer anti-reflection coating with water-repellent properties. It is ideal for photographers and videographers looking to deepen blue skies, manage glare, and achieve more vibrant images.

Advantages
