Voigtlander is an old brand of German origin, now belonging to Cosina.
Cosina is a Japanese contract manufacturer – their 35mm cameras were adopted and sold successively by Canon, Olympus, Nikon, Contax and Zeiss, and they are one of the few companies still producing 35mm film cameras today. A few years ago, they started manufacturing manual focus prime lenses, available in the Canon EF, Pentax K and Nikon F (AI-S) mounts under the Voigtlander brand.
The lenses made for Nikon cameras had one limitation, though. While perfectly compatible with manual focus SLRs, they did not have the electronic chip and the electrical contacts needed to communicate with recent autofocus bodies. Like Nikon’s own AI-S lenses, they could be mounted on mid-level dSLRs like the Nikon D80 or D90, but they were not recognized by the camera, which disabled its exposure metering circuit and forced the photographer to use a hand-held exposure meter, or to rely on the analysis of the histogram, after the picture was taken. The lens mount of higher end Nikon models such as the D300 or the D700 still has the pins, levers and springs needed to be fully AI-S compatible.
The new generation of Voigtlander SL II lenses has the right chip and the right electrical contacts, and is now compatible with any Nikon autofocus SLR or dSLR (the photographer still has to focus manually, of course).
A few days before the PMA, Cosina presented the APO-Lanthar 90mm f:3.5 SL II Close Focus lens (yes, that’s its name), a compact close focus lens. It targets a small niche of photographers who still want to buy new manual focus equipment. With a maximum aperture of F:3.5, it’s pretty slow compared to Nikon’s 85mm f:1.4 prime, and will not compete in the “portrait lens” category. With a magnification ratio of 1/3.5, it’s not a macro lens either. It’s available in Nikon and Pentax mounts, but non in Canon’s EF.
A product for a niche within a niche, obviously.
