Hoya 52mm HD3 Circular Polariser Filter

The Hoya 52mm HD3 Circular Polariser Filter reduces reflections and glare from non-metallic surfaces such as water and glass, while increasing colour saturation and contrast in skies and foliage. Engineered with 16-layers of anti-reflective nano-coating, this professional-grade filter delivers over 92% light transmission, making it ideal for autofocus and exposure accuracy. The lightweight, low-profile aircraft-grade aluminium frame maintains perfect optical alignment for maximum sharpness, whilst the waterproof and stain-resistant coating keeps the glass clean longer.

• 16-layer nano-coating technology delivers superior scratch, stain and water resistance
• Optical-thin HRT polarising film passes 2/3 of a stop more light than standard filters for faster autofocus
• Re-certified for 100MP+ camera sensors without resolution loss
• Low-profile design minimises vignetting on ultra-wide angle lenses
• Front filter threads allow stacking with additional filters or protective lens caps
