UV light's blue haze softens details and image quality, especially on hazy days. This UV Plus+ filter cuts out 99.6% of ultraviolet light for sharper details.
Made from industry-leading German B270 Schott optical glass, which is coated with a 30-layer nano-coating for improved sharpness and added protection. The coating also resists water, oil, and abrasions for long life and easy cleaning.
