Hoya 40.5mm Fusion One Circular Polariser Filter

Hoya Fusion One Circular Polariser Filters have been designed to match the rigorous standards and optical capabilities of modern, high-resolution lenses. Features include multi-layer coating, ultra-high light-transmission, professional-grade optical glass and a low-profile filter-frame. They additionally incorporate stain resistance and a water-repellent coating.

Light rays which are reflected by any surface can become polarised and polarising filters can be used to select which light rays enter your camera lens. CIR-PL (Circular Polarising) filters allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also enable colours to become more saturated and appear clearer with better contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds. HOYA's polarising filters do not affect the overall colour balance of a shot.
