According to Photorumors, a couple of Cosina Voigtländer lenses will soon be released for the relatively new Nikon Z-mount, two for full-frame, one for APS-C. The latter will also be available in a version for Fujifilm X. In order:
Voigtländer APO-LANTHAR 50mm f/2 and 35mm f/2 for Nikon FX with Z-mount.
The Voigtländer APO-LANTHAR 50mm f/2 for Nikon FX (full frame) should be largely similar to the already available version for Sony E - as there, the optical construction comprises 10 elements in 8 groups with an apochromatic design that should prevent chromatic aberrations. The closest focusing distance is 0.45m and the aperture consists of 12 blades. Whether the aperture is optionally unclickable, as with the Sony E version, cannot be inferred from the spec sheet; these optics do not yet show up at Cosina itself. The dimensions are Φ67.6 × 64.3mm with a weight of 347g.
The wider-angle Voigtländer APO-LANTHAR 35mm f/2 for Nikon FX (full frame) also offers an apochromatic design. It consists of 11 elements in 9 groups and weighs 360g. The closest focusing distance here is 0.35m, the aperture is also 12-lens, the length of the lens measures 70.4mm with a 67.6mm diameter (as with the 50mm).
For Nikon&s DX format (APS-C) the Voigtlander NOKTON D23mm f/1.2 is calculated. Here the optical construction consists of 10 elements in 6 groups, including an aspherical lens and two with anomalous positive partial dispersion. The optics offers a minimum focusing distance of 0.18m and also an aperture with 12 blades. The weight is 240g.
The NOKTON D23mm f/1.2 will also appear with a Fujifilm X-mount (weight 214g).
All lenses are designed for manual operation but apparently support focusing aids like peaking, also electronic contacts for EXIF information are available. Pricing and availability details are still pending.
