Zeiss Touit 2.8/12 E-Mount

Affording an especially broad, 18mm equivalent field of view, the Sony E-mount 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.

Wide-angle prime is designed for APS-C-format Sony E-mount mirrorless cameras and provides an 18mm equivalent focal length.
Bright f/2.8 maximum aperture suits working in available-light conditions and is also ideal for astrophotography use.
Distagon optical concept affords high sharpness, well-corrected image quality from edge-to-edge, and very low field curvature.
The optical design utilizes three anomalous partial dispersion elements to reduce color fringing and chromatic aberrations for increased clarity and color fidelity.
Two aspherical elements control distortion and spherical aberrations in order to produce greater sharpness and more accurate rendering.
ZEISS T* anti-reflective coating has been applied to each lens surface to help minimize reflections and provide greater contrast and color fidelity.
Floating elements system helps to maintain consistent image quality throughout the entire focusing range, from 7.1" to infinity.
DC autofocus motor delivers quick and quiet focusing performance to suit both stills and video shooting applications.
