Hoya EVO ANTISTATIC 40.5mm Circular Polarizer - 18-layer (SHMC) Multi-Coating

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.

• Antistatic layer for worry-free cleaning

• The filter features a lightweight, two-piece, low-profile aluminum frame to house the glass. This low-profile frame eliminates vignetting when used on ultra-wide angle lenses.

Circular polarizing filters allow photographers to achieve creative, in-camera, effects not possible after the image is developed. A polarizing filter simply filters out unwanted reflections from non-metallic surfaces such as water and glass in addition to light reflecting off moisture and pollution in the atmosphere. By rotating the ultra-smooth filter, you can select just the right amount of filtration needed to achieve the desired effect. This results in bluer skies, greener leaves, reduced or eliminated reflections on glass, and greater clarity in your final image.
