Cosina Voigtländer (often abbreviated CV) refers to photographic products manufactured by Cosina under the Voigtländer name since 1999. Cosina leases rights to the Voigtländer name from RINGFOTO GmbH & Co. ALFO Marketing KG in Germany. Cosina Voigtländer products have included 35mm film SLR and rangefinder camera bodies, and lenses for the M39 lens mount (Leica screw mount), M42 lens mount, Leica M mount, and other lens mounts.
Cosina started producing cameras and lenses under the Voigtländer brand in 1999, when it introduced a new M39 mount body and lenses. It has since produced a prodigious variety of these lenses in M39x26, Leica M mount, Nikon S rangefinder mount (some fully usable with Contax RF bodies), and SLR mounts including M42 and Nikon F. Cosina produces hoods and accessory viewfinders for many of the lenses. Note that while the lenses feature familiar Voigtländer names, the optical formulas are all new.
Most of the traditional Voigtländer lens brand names remain in use with Cosina, though the lens designs used by Cosina are generally different from the historical namesakes. However, Heliar lenses will still generally have slow apertures, Noktons are for fast apertures, APO-Lanthars will have above-average correction of chromatic aberrations and use many low-dispersion glass elements, while Skopars are compact and light lenses.
Nikon Z-mount
Cosina offers the following lenses with Nikon Z-mount as of 2023. These lenses offer electronic coupling to the camera for recording EXIF data, focus confirmation and IBIS activation.[1]
Sony E-mount
Since October 2015, numerous Voigtländer lenses have been released for full frame Sony E-mount.
Leica M-mount
50mm f/1.5 Nokton
75mm f/1.8 Heliar Classic
15mm f/4.5 Super Wide Heliar Asph. III
At present (March 2018), there are 16 lenses for the Leica M-mount,[20] which can all be combined with rangefinder except the 10 mm lens.
35 mm SLR lenses (SL II series)
Voigtländer SL II lenses are CPU-enabled manual-focus designs available in Nikon AI-P (AI-S with Program), Pentax K-A and Canon EF mounts. The Nikon term for such a design is AI-P, although these lenses are not designated as such. The CPU of SL II lenses enables full compatibility (except for autofocus) with the full range of AF Nikon SLR cameras.
The Nikon AI-P versions enable full compatibility (except for autofocus) with all Nikon AF SLRs, similar to the AI-P manual-focus lenses Nikon has produced in the past. All metering patterns in 2-D mode, all program modes, and viewfinder focus indicators are available.
Micro Four Thirds
Super Nokton 29 mm F0,8 – the fastest lens available off-the-shelf in 2021[39]
On August 26, 2010, Cosina joined the Micro Four Thirds Standard Group[40] and have since introduced the following lenses:[41]
Discontinued lenses
Several lenses, which were manufactured in the past, have now been discontinued.[48]
