The Voigtländer Nokton 40mm F1.2 Leica M is a short, normal primitive lens with Leica M mount that is characterized by its speed. The lens combines a comfortable focal length with an impressive fast f/1.2 maximum aperture. This ensures remarkable control over depth of field. This diaphragm also offers advantages when working in situations with difficult lighting. In addition to the fast design, an optical layout is used that uses two aspherical elements to suppress spherical aberrations and distortion for remarkable sharpness, clarity and accurate rendering. Thanks to the lens's manual focus design, you can work with subjects that are only 35 cm away, and with a selective aperture control system, you can silence the manual aperture ring for a smooth, noiseless exposure setting when shooting movies.
