The Irix Edge Circular Polarizer (CPL) filter is designed for landscape and architectural photography. It ensures the reduction of reflections from non-metallic surfaces, enhances details, and increases color saturation. The glass surfaces of the Irix polarizer feature multi-layer anti-reflective coating for a clear image with natural colors. Additionally, the waterproof and oil-repellent coating protects against stains and fingerprints, allowing usage in extreme weather conditions.
