Voigtländer Nokton Classic 40mm f1.4 with LH-6 eyecup and some minor dust inThe Voigtlnder Nokton Classic 40mm f1. 4 lens is a fast, compact M mount lens. The 40mm focal length is a nice slightly wider field of view that is well suited to rangefinder shooting, at least in the opinion of this description writing person. In excellent condition, with minor dust and good function, only minor cosmetic paint wear. Includes a genuine LH 6 lens hood.
