This Blue Multi-Coated UV Filter from K&F Concept
fits lenses with a 49mm filter thread, providing ultraviolet filtration
to reduce haze, with the added benefit of protecting the lens from
dust, debris, fingerprints, and impact. Made of Japanese optical glass,
this filter also features multi-coating to reduce potential internal
flare and glare. The slim profile design of this filter allows it to be
used on wide-angle lenses without vignetting.
