Urth 46mm UV Lens Filter. Ultraviolet filter protects your lens from scratches, dirt and water. And by removing the UV haze, your images become brighter and sharper. UV light can cause a blue colour cast, but the UV filter cuts 99.6% of ultraviolet light and helps make your images sharper, especially in hazy conditions. Always keep the UV filter on your lens without affecting your exposure settings. If you drop your camera, the UV filter can be the difference between changing a filter and replacing a lens. Japanese AGC glass The high-quality Japanese AGC glass features an 8-layer nano-coating for better sharpness, extra protection and easier cleaning. Ultra-slim magnalium edge The deliberately designed ultra-slim edge prevents vignetting and our durable magnalium has a lifetime guarantee.
