The Voigtlander 50mm f3.5 APO-LANTHAR Type I is an extremely high
performance manual focus standard lens optimized for full frame VM mount
cameras. 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 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.
The filter diameter is a retro inspired φ34mm. Two versions of Type I
are available: a two tone black paint and chrome model with a heavy
feel using brass materials (body weight: 245g) and a lightweight model
with a matte black paint and aluminium construction (body weight: 150g).
