Used Voigtlander Ultron 28mm F/1.9 | M39 | U8

The Voigtländer Ultron 28mm f/1.9 Aspherical is a discontinued, fast wide-angle prime lens designed for M39 screw-mount rangefinder cameras. Produced by Cosina in the 2000s, it offered street and documentary photographers a bright f/1.9 aperture at a fraction of the cost of contemporary Leica equivalents. Its 9-element optical formula incorporates an aspherical element that delivers sharp central resolution while exhibiting a classic, gentle glow and noticeable vignetting when shot wide open. Stopping the aperture down to f/4 or smaller dramatically improves edge-to-edge contrast and sharpness across the 75-degree field of view. Thanks to its universal M39 thread mount and full rangefinder coupling, it remains a popular, character-rich option for both vintage screw-mount bodies and adapted Leica M cameras.
