Voigtlander 90mm f/3.5 APO-Lanthar SL Manual Lens for Contax/Yashica C/Y-Mount Review

The Voigtlander 90mm f/3.5 APO-Lanthar SL is a compact manual-focus telephoto prime designed for Contax/Yashica C/Y mount cameras. It features apochromatic correction for improved color accuracy and sharpness, a hallmark of Voigtlander's Lanthar optical designs. At 90mm, it serves as a short telephoto suitable for portraiture, detail work, and general shooting on both film and adapted digital systems.

This is a legacy lens, so it requires manual focus and aperture control. The C/Y mount makes it straightforward to adapt to modern mirrorless cameras via readily available adapters, which can extend its utility for creators looking for character-rich optics at a modest price. The relatively slow f/3.5 maximum aperture keeps size and weight down but limits low-light flexibility and shallow depth of field compared to faster alternatives. At an MSRP of $330, it occupies the budget end of the specialty lens market, appealing to those who prioritize optical quality and compact form over speed and modern conveniences.
