The Kenko Smart MC UV Filter eliminates ultra-violet rays which can
sometimes cause a hazy, blue cast in outdoor colour photography. UV
filters also protect the front element of your lens against dust,
moisture and scratches.UV filters are especially useful when
photographing scenes such as mountains, beaches, areas of snow, and any
other situations where there is a lot of UV light present. The slim
frame is idea for wide-angle lenses and the multi-coated glass helps
prevent flare and ghosting.
