Voigtlander Nokton 21mm f/1.4 Aspherical FE Lens is available for Pre-Order ($1,099 from B&H | Adorama) is an ultra-wide prime characterized by its impressively bright f/1.4 maximum aperture for working in low-light conditions and controlling depth of field. An advanced optical design incorporates a pair of aspherical elements and three partial dispersion elements, which, together, help to suppress both spherical and chromatic aberrations for greater sharpness, clarity, and color rendering.

A floating elements system is also employed to maintain consistent image quality throughout the focusing range. The lens’s manual focus design permits working with subjects as close as 9.8″ 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. Additionally, a 12-blade diaphragm contributes to a pleasing bokeh quality.
