APO-LANTHAR 50mm F3.5 Type I VM
Super high performance lens in a classic design - Interchangeable lens for VM mount rangefinder cameras
The APO-LANTHAR 50mm F3.5 Type I is an extremely high performance manual focus standard lens optimized for full size VM-mount sensors.
The apochromatic design thoroughly eliminates chromatic aberration on axis and other aberrations, while pursuing ultimate performance in terms of resolution
and contrast reproduction. While adopting a maximum aperture of F3.5, the lens is composed of eight elements in six groups, four of which are made of
anomalous partial-dispersion glass to achieve uncompromising optical performance 
The Voigtländer APO-LANTHAR 50mm F3.5 Type I VM lens combines ultimate optical performance with easy handling and classic vintage rangefinder lens styling.
As a tribute to classic rangefinder lenses that appeared in the mid-20th century, the more expensive vintage style straight slot screw heads were chosen instead of
less expensive modern Phillips head. 
Equipped with a high-precision rangefinder-linked mechanism, and the silky feel of the all-metal helicoid allowing the photographer to experience the true
joy of focusing using a traditional rangefinder. The minimum focusing distance of the Type I is 0.45m. The rangefinder close focus is 0.7m (depending upon camera capability),
which is linked to the rangefinder.
A mechanism is provided to recognize the junction point of the rangefinder-linked range by a clicking sensation during focusing operation.
