Announcing Voigtländer MACRO APO-LANTHAR 110mm F2.5, a
Sony E-mount 1:1 macro lens for full frame sensors incorporating
an apochromatic optical design and inscribed with the designation
“APO-LANTHAR”
Cosina Co., Ltd. is releasing Voigtländer MACRO APO-LANTHAR 110mm
F2.5, a 1:1 macro lens designed exclusively for full frame Sony E-mount
cameras. 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 MACRO APO-LANTHAR 110mm F2.5 is a high performance manual focus 1:1 macro lens optimized
for the imaging sensors of Sony mirrorless cameras. Inheriting the APO-LANTHAR designation, the lens is highly
corrected to eliminate optical aberrations including longitudinal chromatic aberration. Retaining a similar form
factor to the highly regarded Voigtländer MACRO APO-LANTHAR 65mm F2.0 Aspherical we released in August
2017, this lens covers the full frame image area, and achieves a maximum image reproduction of 1:1 life size with
no additional attachments. In order to ensure subjects from minimum focus distance to infinity are captured with
extremely high image quality, a 3-group floating mechanism is employed to adjust three optical groups according
to focus distance. The 110mm focal length on full frame format ensures not only a good working distance from
subjects for macro shooting, but also its angle of view for portraiture does not look too cropped in comparison with
135mm and 200mm lenses. Another attractive feature is the ability to create images with a strong out-of-focus
‘bokeh’ effect, made possible by the 110mm focal length and F2.5 maximum aperture. 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.
