The Leica E39 UV Silver Finish Filter precisely annealed and made from optically pure glass and parallel plane ground. The Leica E39 UVA IR Filter shields the front element of the camera and you can also leave it permanently attached to the camera.

• The Leica E39 UV Silver Finish Filter offers high performance
• It is used only in photographic practices
  

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. The circular polarization filter eliminates disturbing reflections on non-metallic surfaces, and helps to increase contrast as well as provide richer color reproduction.

A characteristic of polarization filters is that they show the same effect after each 180-degree rotation. The polarization filter for the Leica M is thus supplied with an adapter with a swivel fitting, allowing it to be rotated 180 degrees to in front of the viewfinder so you can assess and control its effect before taking the shot.
