40mm f/1.2 Nokton ASPH M-mount Lens
A fast short normal prime for Leica M-mount rangefinder cameras, the Nokton 40mm f/1.2 Aspherical Lens from Voigtlander is an excellent choice for working in low-light conditions and offers notable control over depth of field for producing shallow depth of field imagery. Its unique 40mm focal length offers a 55° angle of view that is slightly wider than the classic 50mm length, yet narrower than the standard 35mm wide-angle.
Complementing the fast design is an optical layout that uses two aspherical elements to suppress spherical aberrations and distortion for notable sharpness, clarity, and accurate rendering, and a rounded ten-blade diaphragm contributes to attractive out of focus areas. The lens's manual focus design permits working with subjects as close as 50 cm away, and it is also rangefinder coupled to 2.3' for working with optical focusing systems.
