Affording an especially broad, 18mm equivalent field of view, the Touit 12mm f/2.8 from ZEISS is a prime wide-angle lens well-suited for landscape, architecture, and interior shooting. A sophisticated Distagon optical design includes two aspherical elements and three low dispersion elements, which help to control a variety of aberrations, distortion, and color fringing in order to produce sharp, well-corrected imagery. A floating elements system is used, too, to maintain consistent image quality throughout the focusing range. Individual elements also receive a ZEISS T* anti-reflective coating to suppress flare and ghosting for greater contrast and color accuracy when working in strong lighting conditions. Additionally, suiting both photo and video use, this lens incorporates a DC autofocus motor to deliver especially fast, quiet, and precise focusing performance.
