Urth 49mm UV Lens Filter (Plus+) Ultra-Slim 30-Layer Nano-Coated UUVPL49

This 49mm UV Lens Filter (Plus+) from Urth cuts ultraviolet light to sharpen images while protecting lenses from scratches, oil, knocks, and water. By cutting UV light's blue haze, the UV Plus+ filter improve sharpness and clarity in photographs, but doesn't affect camera settings, which means it can be left on a lens at all times. 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.
