Voigtlander's updated fast 35mm for Leica M — the Ultron Type II with improved optics.
The Voigtlander Ultron 35mm f/2 Aspherical Type II VM is the updated version of Voigtlander's compact fast 35mm for Leica M mount (Type I described under ID 4038). The Type II improves the optical design with better wide-open performance and digital sensor compatibility. The Ultron rendering is clean and modern — clinical precision rather than vintage character.
Optical performance is very good — improved over the Type I. Sharpness is excellent from f/2 with the updated aspherical element providing better edge correction on digital M sensors. Colour rendition is neutral and precise. The Ultron character is distinct from the Nokton Classic — sharper and more clinical at wide apertures. Well-suited to digital M bodies.
Leica M mount with rangefinder coupling. Filter thread is 39mm (E39). Weight is approximately 200 grams — compact. Build quality is outstanding Cosina precision with metal construction. Manual focus with smooth helicoid. The Type II update specifically addressed digital sensor compatibility — reducing colour shift and improving corner performance on M digital bodies.
Available on the used market at moderate prices. Check rangefinder coupling and smooth focus. The Type II is preferred over the Type I for digital M use. An excellent compact fast 35mm for M-mount — the Ultron clean rendering and improved digital compatibility make it one of the most practical M-mount 35mm options.
