The Voigtländer 75mm f/1.9 Ultron S.C. (Single Coated) represents a refined modern interpretation of the classic short telephoto lens for the Leica M system. This specific variant, distinguished by its single coating (S.C.) and a glossy black paint finish, has been meticulously designed for photographers who favor the aesthetic of film and black-and-white photography. Compared to the multi-coated version, the Ultron S.C. offers slightly lower contrast and a controlled tendency toward flare and stray light—characteristics that lend images a depth and “vintage” character difficult to replicate in post-production. The optics employ a 7-element, 5-group design, utilizing three partial-dispersion glass elements to correct chromatic aberrations while maintaining a deliberate and moderate spherical aberration aimed at maximizing the smoothness of the bokeh. One of its most notable features is the minimum focusing distance of just 50 cm, an exceptional value for rangefinder systems that allows for superior creative versatility in close-up portraiture. The 12-blade diaphragm ensures perfectly circular highlights at all apertures, while the all-metal construction guarantees the mechanical precision required for micrometric coupling with the rangefinder of Leica cameras.
