The 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 Hoya multi-coating (HMC) formula that greatly reduces or eliminates reflections on the surface of the glass and yields a 99.8% light transmission rate. This means the filter has virtually no effect on color balance, contrast, or clarity of the final image.
