The Hoya 52mm Slim Circular Polariser Filter means that you can significantly reduce reflections & glare from non-metallic surfaces. A camera angle of 30 degrees from the reflecting surface (glass, water, etc.) is ideal for maximum effect. The Circular Polariser Filter also enables colours to become more saturated & appear clearer with better contrast. This effect is often used to increase the contrast & saturation in blue skies & white clouds. The Hoya 52mm Slim Circular Polariser has a thin frame to reduce vignetting when using wide angle lenses, but still allows a clip-on lens cap to be used. Hoyas polarising filters do not affect the overall colour balance of a shot.
