Japanese lens maker Cosina has announced the Voigtlander APO-Lanthar 50mm f/3.5 Type I and Type II lenses in VM mount, suitable for use on Voigtlander and Leica rangefinder cameras, plus a wide array of modern full-frame mirrorless cameras through the use of an adapter.
As spotted by Asobinet in Japan, there are technically two new lenses. They are both compact 50mm f/3.5 lenses with an identical apochromatic optical design but differ slightly in size, weight, appearance, and focus distance.
The “type” refers to a different lens barrel design. The “Type I” version sports a thinner, slightly lighter barrel with a 34mm filter thread, while the “Type II” variant has a more traditional profile that is a bit beefier; it has a 39mm filter thread.
Depending on the selected material, the 50mm f/3.5 Type I weighs either 150 grams (5.3 ounces) in its matte black paint version or 245 grams (8.6 ounces) in its two-tone black and silver colorway. The Type II lens is available in black paint (175 grams / 6.2 ounces) and silver (250 grams / 8.8 ounces). In both cases, the lenses are built with retro styling in mind and are comprised of metal.
The optical designs are the same for each type. The lens features eight elements arranged across six groups, including four pieces of anomalous partial-dispersion glass. Cosina says the lens offers “uncompromising optical performance.” Due to the apochromatic design, the lens promises to “thoroughly eliminate” various aberrations, including chromatic ones. The lens has a 10-bladed, manually controlled aperture diaphragm.
The manual focus lenses feature a high-precision rangefinder coupling mechanism, which couples from 0.7 meters (2.3 feet) to infinity, depending on the specific camera used. It is worth noting that the minimum focusing distances differ slightly between the two lens types, with the Type I focusing at 0.45 meters (1.48 feet) and the Type II version getting a bit closer: 0.35 meters (1.15 feet).

Pricing and Availability
Cosina says the new Voigtlander APO-Lanthar 50mm f/3.5 Type I and Type II lenses will be available in August. While North American pricing has yet to be announced, based on Japanese pricing, the lenses should cost around $550-650, depending on the type and material finish. The new lenses will join the existing Voigtlander APO-Lanthar 50mm f/2 Aspherical, which is available now for $999.
