The HOYA 72mm Circular Polariser HD3 Filter reduces reflections and glare from non-metallic surfaces whilst boosting colour saturation and improving overall image contrast. Engineered for 100MP+ camera sensors, the HD3 utilises a 16-layer nano-technology multi-coating and premium optical-thin HRT (high rate transmission) polarising film that passes approximately two-thirds of a stop more light than standard filters. The ultra-hard nano coating provides scratch and stain resistance whilst remaining easy to clean, and the lightweight aircraft-grade aluminium frame features a low-profile design to minimise vignetting on ultra-wide angle lenses. The dual filter rings with knurled edges allow smooth rotation to achieve optimal polarising effects and easy attachment and removal. Perfect for landscape and creative photography where you need to enhance sky colour, reduce water reflections and improve clarity.
