Voigtländer APO-Ultron 90mm f/2 VM

The Voigtländer APO-Ultron 90mm f/2 VM is a modern apochromatic short-telephoto lens for Leica M and VM-mount rangefinder cameras. Manufactured by Cosina under the Voigtländer brand, it was released in January 2025 as a compact high-performance 90mm f/2 lens with rangefinder coupling and full-frame 35mm coverage [1][3]. It occupies a premium position in the modern Voigtländer VM lineup, offering a fast portrait-length focal length, apochromatic correction, and a smaller body than many traditional 90mm f/2 rangefinder lenses.

The lens uses an 8-element, 7-group optical construction, with six of the eight elements made from abnormal partial dispersion glass [1]. Cosina lists the lens with a 90mm focal length, f/2 maximum aperture, f/16 minimum aperture, 12 aperture blades, 0.9 m minimum focus, 52 mm filter thread, 61.9 mm maximum diameter, 63.3 mm length, and 340 g weight [1]. The VM mount is compatible with Leica M cameras and is rangefinder coupled from infinity to 0.9 m, although the effective coupled range can depend on the camera body [1][2].

For LeicaLensList, this entry should be treated as a native VM / Leica M lens rather than an adapted mirrorless lens. It should be kept separate from the Voigtländer APO-Skopar 90mm f/2.8 VM, older Voigtländer 90mm lenses, and Leica’s APO-Summicron-M 90mm f/2 ASPH. The APO-Ultron 90mm f/2 VM is collector-relevant because it combines modern Cosina Voigtländer production, high optical correction, rangefinder coupling, two factory finishes, compact handling, and a dedicated reversible metal bayonet hood [1][2].

History

Development and Launch

Cosina announced the Voigtländer APO-Ultron 90mm f/2 VM on 13 December 2024 and later confirmed a Japanese release date of 23 January 2025 [3]. The lens was introduced as a fast compact apochromatic VM portrait lens, designed specifically for M-mount rangefinder cameras and full-frame 35mm use [1]. It followed Cosina’s broader development of high-correction Voigtländer APO lenses, including the APO-Lanthar and APO-Skopar lines.

Production Evolution

The APO-Ultron 90mm f/2 VM entered the Voigtländer VM lineup in 2025 and remains listed in black and silver versions by Cosina and Voigtländer Germany [1][2]. Official specifications identify the black version with article number 121396 and EAN 4002451008518, while the silver version is listed as article number 121395 and EAN 4002451008501 [2]. No optical revision or discontinued status is documented in the official sources used for this entry.

Special Variants

The main documented factory variants are the black and silver finishes [1][2]. Both share the same optical formula, dimensions, weight, filter thread, minimum focus distance, aperture blade count, rangefinder coupling, and supplied bayonet hood. No limited edition, brass edition, special color, anniversary version, or alternative optical version is widely documented as a standard factory variant.

Collector Notes

Collectors should verify the finish, article number or EAN where available, supplied reversible bayonet hood, front cap, rear cap, original box, and VM mount condition. Since the lens is not Leica 6-bit coded, digital Leica M users may need to select a manual lens profile if desired. Important condition checks include rangefinder coupling accuracy at f/2, smooth focusing, aperture click feel, hood bayonet condition, filter thread condition, coating marks, internal dust, and signs of impact around the relatively compact front barrel. The lens should not be confused with the slower APO-Skopar 90mm f/2.8 VM or with non-M adapted 90mm lenses.
