UV light can create a blue colour 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 colours, and greater depth. Sharper photos Cuts UV light for sharper images. Extra protection Extra protection to save your lens from damage. Cut haze and cast Cut UV haze and blue colour cast for truer colours. Professional German glass Industry-leading German B270 SCHOTT optical glass is coated with a 30-layer nano-coating for better sharpness, added protection, and easier cleaning.
