A favored focal length among street photographers and journalists, the black Ultron 35mm f/1.7 Aspherical Lens from Voigtlander is a standard wide-angle prime designed for use with M-mount rangefinder cameras. The versatile focal length is complemented by the fast f/1.7 maximum aperture, which benefits working in a variety of lighting conditions and also offers enhanced selective focus control. The lens construction incorporates a single aspherical element to reduce spherical aberrations and distortions for increased sharpness and clarity, and the ten-blade diaphragm helps to achieve a smooth, pleasing bokeh. This manual focus lens permits focusing as closely as 1.6' away and depth of field and distance scales aid in pre-focusing and zone focusing techniques.
