The K&F Concept Blue Multi-Coated UV Filter is compatible with lenses that have a 49mm filter thread, providing ultraviolet radiation filtering to reduce haze, while protecting the lens from dust, debris, fingerprints, and scratches. Made from Japanese optical glass, this filter features multi-layer coating to reduce potential internal flares and reflections. The slim design of the filter allows for use on wide-angle lenses without creating vignetting.
