Hoya engineers have developed a new ANTISTATIC coating that acts like a static-negating force-field around the filter to prevent dust from being attracted to the surface of the glass during cleaning. Perfect for environments where dust is common, these filters require less frequent cleaning and maintenance than traditional filters. Additionally, the hardened, antistatic top-layer is water repellent, stain and scratch resistant, and cleans easily when smudges or fingerprints are introduced to the surface. The new EVO ANTISTATIC professional filters are made in Japan using hand selected silicates that are carefully smelted and blended to yield high performance optical glass. Hoya then uses extreme care and precision to apply the improved 18-layer super multi-coating formula which greatly reduces or eliminates reflections on the surface of the glass and yields very high light transmission rates. This means the filter has virtually no effect on the color balance, contrast, or clarity of the final image beyond its polarizing effects.
