Versatile Ultra-Wide Prime. The Voigtlander 21mm f/1.4 Nokton for Sony E’s combination of ultra-wide focal length, fast aperture, and twelve-blade diaphragm makes it ideal for landscapes, interior photography, architectural photography, and any application in which you need subject-background isolation. This lens is compatible with APS-C cameras, on which it’ll produce an 31.5mm focal length.

Fast Maximum Aperture. This lens’s fast f/1.4 maximum aperture gives you great low-light performance and excellent depth-of-field control for using selective-focusing techniques.

Advanced Optics. The 21mm f/1.4’s eleven-group/thirteen-element optical design includes two aspherical elements and three abnormal partial-dispersion elements, which provide exceptional sharpness and clarity while preventing spherical aberrations and distortion. The floating-elements system maintains consistent image quality throughout the aperture range to suit working with distant and close-up subjects.

Manual Focus and Aperture. This lens’s manual-focus design gives you smooth, precise control over focus placement, and it has a ten-inch minimum focusing distance to let you get in close. Even though this is a manually focusing lens, it transfers EXIF data to the camera so that you can use in-camera stabilization, magnification, and other features.

Selective Aperture Control System. The 21mm f/1.4’s Selective Aperture Control System gives you a stepless, de-clicked aperture ring that provides smooth and silent exposure adjustment that’s perfect for video applications. You can also configure the aperture ring to use traditional 1/3-stop clicks for more tactile control over exposure settings.
