Concurrently with the Voigtlander APO-Lanthar 50mm F2 Aspherical lens, Cosina has introduced a second lens with a Nikon Z mount. This is the Voigtlander Nocton D23mm F1.2 Aspherical. Unlike the Voigtlander APO-Lanthar 50mm F2 Aspherical, this is not a full frame lens. It covers the APS-C or Nikon DX format frame, to use Nikon designations. Of course, the new lens can also be mounted on a full-frame camera (Nikon FX) by selecting the frame shooting mode.
Focus and aperture control are manual. According to the manufacturer, the 12-blade aperture provides beautiful out-of-focus blur. The lens also boasts high resolution throughout the frame due to the inclusion of a double-sided aspherical element and two elements with an abnormally low dispersion in the optical design. Designed for use with Nikon Z cameras, the lens feeds the camera the data required for EXIF recording and the three degrees of freedom image stabilization and three focus indication modes.
