A multi-purpose filter which absorbs ultraviolet rays that often make outdoor photographs hazy and indistinct. UV filters are colourless and can be used in combination with other filters. They are also recommended as a general lens protector, to leave on lenses at all times – this protects the front element from scratches, dust and moisture. The NX-10 UV has 10 layers of anti-reflective coating, to reduce ghosting and flare, providing 98% light transmission. The slim filter frame avoids vignetting with wide-angle lenses.
