This is the ultimate clear filter. It will not affect the color balance or performance of your lenses in the slightest. However, with regular use, it will protect your valuable lenses from costly damage to the front element caused by dirt, impacts, or scratches. The ultra-clear high-transparency glass has been chemically enhanced and quadruple reinforced. The double-sided 16-layer anti-reflective multi-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 has been mounted using high-pressure pressing technology.
