At the same time with lens Voigtlander APO-Lanthar 50mm F2 Aspherical Cosina introduced the second Nikon Z mount lens. This is the Voigtlander Nocton D23mm F1.2 Aspherical. Unlike the Voigtlander APO-Lanthar 50mm F2 Aspherical lens, this is not a full frame lens. It covers an APS-C or Nikon DX format frame, using Nikon designations. Of course, the new lens can also be attached to a full-frame camera (Nikon FX) by selecting crop mode.
Focusing and aperture control are performed manually. According to the manufacturer, the 12-blade aperture provides beautiful out-of-focus blur. The advantages of the lens also include high resolution over the entire frame, provided by the inclusion of a double-sided aspherical element and two elements with abnormally low dispersion in the optical scheme. Designed for use with Nikon Z system cameras, the lens transmits to the camera the data needed for EXIF recording and for 3-DOF image stabilization and 3 focus-indication modes.
