Voigtlander 50mm f/2 APO-Lanthar E-Mount 108179

Voigtländer APO-LANTHAR 50mm F2.0, standard lens designed exclusively for full frame Sony E-mount cameras. This year 2019 is 20th anniversary of the Voigtländer Classic Line business. Voigtländer APO-LANTHAR 50mm F2.0 is designed as the best performance Voigtländer standard lens of all time.

The APO-LANTHAR designation is given to especially high performance lenses in the Voigtländer lens lineup, with APO being derived from the apochromatic optical design. A need for apochromatic optical designs that reduce the longitudinal chromatic aberrations of the three primary colors (RGB) of light to practically zero arose with the increasing popularity of color film. Now, with the current range of high-resolution digitals sensors, this need for extremely high-level control of chromatic aberrations is even more pertinent than when film changed from monochrome to color in the middle of the 20th century. So rather than just being for already solved old technologies, apochromatic optical designs are indeed a subject requiring serious consideration in the digital age.

Voigtländer APO-LANTHAR 50mm F2.0 is a high performance manual focus standard lens optimized for the imaging sensors of Sony mirrorless cameras. Inheriting the apochromatic optical design, the lens is highly corrected to eliminate optical aberrations including longitudinal chromatic aberration. In addition, it is optimized for the ultimate performance of the resolution and contrast reproducibility. (Ref. MTF chart) The lens constructed with 8 groups 10 elements has five abnormal partial dispersion glasses, two out of eight elements, each with two aspherical surface, and also floating focus system built-in. The lens has a proud performance that will drastically change your image of familiar standard lens “50mm F2”.

Sometimes, engineers seek for the ultimate performance and tend to be too egocentric to increase the lens size or weight which won’t fit the photographers’ joy. Voigtländer lenses must achieve not only uncompromising optical performance, but also the light handling. Voigtländer APO-LANTHAR 50mm F2.0 is the ideal form which has both ultimate optical performance and compactness. It addition, the aperture blades with twelve elements employ special shape that becomes round-shape with not only at F2, but also at F2.8. This enables circular Bokeh effect from point-light source.

This lens is a manual focus and manual aperture design, but also features electrical contacts that enable the lens settings at image capture to be included in the Exif information of the image data. Furthermore, the lens is installed with a distance encoder to enable support for 5-axis image stabilization on bodies with this feature, by providing distance to subject information used to compensate for camera shake. Focus peaking while manual focusing is also supported. The aperture ring has click stops in 1/3 steps. The lens also features a click stop switching mechanism that enables the click stops to be turned off when shooting video.
