Our professional Ultraviolet Filter Plus+ cuts UV light to make your images clearer and sharper and protects your lens from scratches, oil, dirt and water. UV light can create a blue color cast, but our UV Filter cuts out 99.6% of ultraviolet light, helping sharpen your image, especially in hazy conditions. If you drop your camera, our UV Filter Plus+ may be the difference between replacing a filter and replacing your lens. Our UV Filter Plus+ features 30 layers of nano-coating providing easier cleaning and better protection against water, oil and scratches. These layers also provide a higher maximum light transmission and a more consistent transmission curve for sharper images, finer colors, and greater depth.
