The Sigma WR (Water-repellent) range of filters are a new concept that suit the new “SGV” range of high optical performance lenses. Sigma WR filters enable easier handling while shooting and feature excellent water and oil repellent as well as having an antistatic function. These WR filters are available in various sizes, both in “UV”, “Circular PL (Polarizing)” and Clear-Glass Protector. Interchangeable lenses are required to perform their best in different shooting conditions and these new range of filters will certainly ensure their performance to the fullest. Circular PL filter removes the reflection of water surface and glass windows, and increases the contrast in landscape photography. Design that is conscious of optical qualityIt is designed to avoid vignetting or the decrease in peripheral light quantities especially when the thinner wide type filters are used with SIGMA lenses. Ultra Low-reflectionBy incorporating Sigma’s Super Multi-Layer Coating, the filter reduces flare and ghosting. In addition, black rimmed glass eliminates unnecessary internal reflections and provides high performance for both digital cameras and film cameras. Water and Oil-repellent function (SIGMA WR FILTER)With excellent Water and Oil repellent functions, the filter surface repels water drops and provides resistance to fingerprints. Even if they appear on the surface they can be easily removed. Antistatic functionWith excellent antistatic performance, the filter prevents microscopic dust clinging to the surface. Even if the lens gets soiled, dust can be easily removed using an air-blower. Excellent for carrying and long-term storageThanks to Elastomer resin, filters do not move in the case even when it is carried around. The case is half-transparent so that content can be recognized from outside.
