Cosina will release the Voigtlander APO-LANTHAR 28mm F2 Aspherical E-mount wide-angle lens, designed exclusively for full-frame Sony E-mount cameras, in December 2025. The suggested retail price is 154,000 yen (tax included).
APO-LANTHAR is the name given to high-performance Voigtländer lenses, and the “APO” comes from the apochromatic design. Apochromatic design, which minimizes axial chromatic aberration in the three primary colors of light (RGB), is a technology that has been in demand since the advent of color film, and is becoming increasingly important as an advanced chromatic aberration correction method even with today’s increasingly high-pixel digital sensors.
What is the Voigtlander APO-LANTHAR 28mm F2 for E-Mount?
The Voigtlander APO-LANTHAR 28mm F2 E-Mount is positioned as Voigtländer’s high-end wide-angle lens, following the previously released APO-LANTHAR 50mm F2 Aspherical and APO-LANTHAR 35mm F2 Aspherical (excluding macro lenses). Optimized for full-frame Sony E-mount sensors, its apochromatic design thoroughly suppresses various aberrations, including axial chromatic aberration, while pursuing high resolution and contrast reproduction.
The lens is made up of 12 elements in 8 groups, with 6 anomalous partial dispersion glass elements and 2 double-sided aspherical elements. It also incorporates a floating mechanism, ensuring clear, accurate images from a minimum focusing distance of 0.28m to long distances. Its design aims for high image quality in the large-aperture wide-angle lens category at 28mm F2.
The overall length from the mount is compact at 58.8mm, shorter than the semi-wide-angle lens “APO-LANTHAR 35mm F2 Aspherical.” The 12-blade aperture is nearly circular, designed to naturally capture bokeh effects, including point light sources.
This lens is equipped with electronic contacts, and when paired with a compatible camera body, lens information can be recorded in the Exif information of the shooting data. It also has a built-in distance encoder, making it compatible with cameras equipped with 5-axis in-body image stabilization that uses subject distance information. It also supports viewfinder magnification linked to focus ring operation, supporting precise focusing when using manual focus.
The aperture ring has 1/3-stop clicks and is equipped with a clickless aperture switch mechanism for video shooting. A metal circular screw-on hood is included as an accessory, allowing for compactness when attached.
