State-of-the-art optics in a lightweight, compact exterior. VM/L (L39) mount interchangeable lens for rangefinder cameras, either M or Leica Thread Mount (L=LTM.) The COLOR-SKOPAR 28mm F2.8 Aspherical VM/L (L39) is a high-performance wide-angle lens focused on light handling for rangefinder cameras. The latest optical design and aspherical lens elements maintain the same optical performance as our Voigtländer ULTRON Vintage Line 28mm F2 Aspherical VM, while keeping the maximum aperture at F2.8 to achieve extreme portability. Type II has a modern style with a straight helicoid system. The lens exterior is made of aluminum to further reduce weight. It is available in black and silver finishes. All six models have extremely compact exteriors, and the lenses combine the mobility of a rangefinder camera with the beautiful design of a snap-shooter. (With designated finishes and mount to each model as described.) The optical system consists of 8 elements in 5 groups, including one double-sided aspheric lens. The lens has been optimized for use with rangefinder linked digital and film cameras. It is also easily used with mirrorless digital cameras by using Voigtländer mount adapters. All models include metal screw-in lens hood and metal front cap.
