Voigtlander's compact fast 35mm for Leica M — the Ultron Type I with f/2 speed.
The Voigtlander Ultron 35mm f/2 Aspherical Type I VM is a compact fast wide-angle prime for Leica M mount. The Ultron designation indicates a premium optical design — more clinical and precise than the characterful Nokton Classic alternatives. At f/2 and 35mm, it covers the classic street photography perspective with useful speed.
Optical performance is very good. Sharpness is impressive from f/2 with the aspherical element providing excellent wide-open correction. The Ultron rendering is clean and modern — distinct from the deliberately vintage Nokton Classic character. Colour rendition is neutral. Distortion is minimal. The Type I is the original version — the Type II updated the optical design.
Leica M mount with rangefinder coupling. Filter thread is 39mm (E39) — matching many Leica lenses. Weight is approximately 200 grams — very compact. Build quality is excellent with precision Cosina metal construction. Manual focus with smooth, precise helicoid. The compact size makes it one of the most portable M-mount 35mm options.
Available on the used market — the Type II has reduced demand for the Type I. Check rangefinder coupling and smooth focus. The Type I Ultron is a clean, modern 35mm for M-mount. The Type II is optically improved. An excellent compact fast 35mm for M-mount street photographers who prefer modern rendering over vintage character.
