The Voigtlander APO-LANTHAR 90mm F4 Close Focus VM is an extremely high-performance manual-focus medium telephoto lens optimized for full-frame M-mount sensors. Through its apochromatic design, it thoroughly suppresses various types of aberrations, including axial chromatic aberration, while also pursuing ultimate performance in terms of resolution and contrast reproduction.
While maintaining the traditional F4 aperture used in 90mm lenses for rangefinder cameras, the lens achieves uncompromising optical performance by incorporating anomalous partial dispersion glass in six of its eight elements across seven groups. Total length from the mount surface is just 54.8mm—about the same as the short side of a credit card. Weighing just 235g, the lens is lightweight, offering excellent portability while eliminating vignetting in the shooting frame when using an optical rangefinder.
