A normal-length prime lens designed for M-mount rangefinder cameras, the Nokton Classic 40mm f/1.4 SC from Voigtlander blends the comfortable, unique focal length with an especially bright f/1.4 maximum aperture, which benefits working in low-light conditions as well as offering increased control over depth of field. This edition of the 40mm f/1.4 also features a single coating, as opposed to a more common multi-layered coating, which offers a subtler image quality with slightly reduced contrast that is especially well-suited to black and white applications. The lens also features a manual focus design, for working with subjects as close as 2.3', and has a 10-blade diaphragm for a smooth bokeh quality.
