History
Introduction2012

The Zeiss Touit 2.8/12 is an interchangeable APS-C wide-angle camera lens announced by Zeiss on September 18, 2012. Zeiss used a Distagon optical design for this lens.[1]

Build quality[]

The lens features a minimalist matte-black plastic exterior with a Zeiss badge on the side of the barrel and a rubber focus ring.

It is robust and very compact considering its ultra wide-angle focal length.

Optical quality[]

The lens is sharp in the center from wide open apertures, but needs stepping down to f/5.6 for corners to catch up.[2]

Chromatic aberrations are well controlled[3] and barrel distortion is visible when not corrected but typical for this kind of wide-angle lens.[4] Also vignetting is visible wide open but is diminished when stepping down.[5]

Resistance to flare is average, with sunstars being produced at f/11.[6]
