Leica E39 UV Silver Finish Filter

The Leica filters for the Leica M system are made of optically pure glass, parallel plane ground and precisely annealed, so the full performance of the Leica M lenses is retained even with a filter attached. The range is purposely limited to the filters most commonly needed in photographic practice: The UVa filter primarily performs the role of protecting the front element of the lens, and can be left permanently attached.
