Review Lens: Carl Zeiss Touit 2.8/50M Sony E

Lens Overview - Carl Zeiss Touit 2.8 /50

A clever short telephoto, the Sony E-mount ZEISS Touit 50mm f/2.8M is a 75mm-equivalent prime suitable for both portraiture as well as close-up shooting. As a macro lens, it features a life-size 1:1 maximum magnification ratio and a minimum focusing distance of 5.9" for working with nearby subjects. Its advanced Planar optical design includes two aspherical elements and two 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.
