This is the ultimate clear filter. It will not affect the color balance or performance of your lenses in the slightest. However, with constant use, your valuable lenses will be protected from costly damage to the front lens caused by dirt, bumps or scratches. The Ultra Clear High Transparency glass has been chemically enhanced and 4-layer reinforced. The double-sided 16-layer anti-reflective multi-layer coating is water and oil repellent, as well as scratch and dirt repellent. The ultra-thin frame is compatible with wide-angle lenses. The glass was mounted using high-pressure molding technology.
