Overview

The Sigma 12mm F1.4 DC Contemporary is an ultra-wide, ultra-fast APS-C lens praised for its compact, lightweight build and smooth handling, including a click aperture ring and quiet autofocus. Optically, it offers very good central sharpness at f/1.4, becoming outstanding by f/2.8, but is not razor-sharp in the center wide open and has strong barrel distortion requiring correction. It suits landscape, night sky, and environmental portrait photographers seeking an ultra-wide prime with a fast aperture.
