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 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 FUSION Antistatic professional filters are made in Japan using hand selected silicates that are carefully smelted and blended to produce high performance optical glass. Hoya then uses extreme care and precision to apply the improved 9-layer Super Multi-coating formula which eliminates or greatly reduces reflections on the surface of the glass, resulting in very high light transmission rates. This means that the filter has virtually no effect on the colour balance, contrast, or clarity of the final image. The FUSION Protector filters feature a lightweight, one-piece, low-profile aluminium 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.
