Hoya engineers have developed a new antistatic coating that acts like a force field around the filter to repel dust. Perfect for environments where dust is common, these filters require less frequent cleaning & maintenance than traditional filters. Additionally, the hardened, antistatic top-layer is water repellent, stain & scratch resistant, & cleans easily when smudges or fingerprints are introduced to the surface. The filter's uv properties filter unwanted ultra-violet rays, reducing haze & increasing clarity. The new evo antistatic professional filters are made in japan using hand selected silicates that are carefully smelted & blended to yield high performance optical glass. Hoya then uses extreme care & precision to apply the improved 16-layer super multi-coating formula which greatly reduces or eliminates reflections on the surface of the glass & yields a 99.8% light transmission rate. This means the filter has virtually no effect on the color balance, contrast, or clarity of the final image. The filters features a lightweight, one-piece, low-profile aluminum frame to house the glass. This one-piece design allows the filter to maintain perfect parallel alignment to the sensor plane for maximum sharpness, while the low-profile form eliminates vignetting when used on ultra-wide-angle lenses.
