The UV filter is a transparent all-purpose filter that helps absorb ultraviolet light. It does not add any extra color or contrast, allowing you to pair it with other filters. The UV filter is also useful as a general protection filter that can be left on the lens at all times. Filters help reduce the ingress of dust and moisture into the lens element and provide additional protection in case of a fall or scratch. This filter is perfect for outdoor shots, reduces blue tones in UV-rich environments, increases image contrast, and removes light haze or fog (e.g., at the sea or in high mountains). It protects the front lens element from damage and features a multi-layer coating as well as a matte black aluminum frame.
