The Kenko 46mm 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.
