The Panasonic 46mm Polarizing Filter helps in reducing the glare during outdoor photography. By filtering out the polarized light from a non-metallic surface, it helps to reduce the reflections from affecting the image. It also increases the saturation of skies and foliage by absorbing the polarized light. In addition to that it also helps in reducing the reflections in glass and on water and also cuts through distant haze in the distant landscape image. It bestows the best effect when used at a 90° from the sun. When used along with wide angle lenses, this slim lens helps in reducing vignetting.
