20mm f/1.4 EX DG HSM Art: Sony E

Wide-angle Prime lens for Sony E Mount

The Sony E mount 20mm f/1.4 DG HSM Lens from Sigma is part of their Art series of Global Vision lenses, and provides impressive optics in a robust body. With its wide focal length it is suited to a range of applications such as landscape, interior, architecture and astrophotography. It features 15 elements in 11 groups, two "F" Low Dispersion (FLD) elements, five Special Low Dispersion (SLD) elements, and two aspherical elements to significantly reduce chromatic aberration, spherical aberrations, and distortion. A Super Multi-Layer Coating further minimizes surface reflections, flare, and ghosting.

A Hyper Sonic Motor compliments this construction with fast and near-silent autofocus, and full-time manual focus override is possible at any time by simply rotating the focus ring. It is constructed from Thermally Stable Composite material with a brass lens mount for durability.
