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 expensive front lens damage that could be caused by dirt, bumps or scratches. The Ultra Clear High Transparency glass has been chemically enhanced and reinforced 4-fold. The double-sided 16-layer anti-reflective multi-layer coating is water and oil repellent, as well as scratch and dirt resistant. The ultra-thin frame is compatible with wide-angle lenses. The glass was mounted via high-pressure molding technology.
