Distinguished by its speed, the Nokton 40mm f/1.2 Aspherical from Voigtlander is a short normal prime designed for full-frame Sony E mirrorless cameras. Its comfortable focal length pairs with an impressively fast f/1.2 maximum aperture to enable notable control over depth of field for producing shallow depth of field imagery, and this aperture also benefits working in difficult lighting. 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. The lens's manual focus design permits working with subjects as close as 1.1' away, and a Selective Aperture Control System allows you to de-click the manual aperture ring for smooth, silent exposure adjustment to suit filmmaking applications.
