The Sigma 56mm f/1.4 DC DN Contemporary is a portrait-length prime lens for APS-C-format Sony E-mount mirrorless cameras. Its bright f/1.4 maximum aperture suits difficult lighting and gives more control over depth of field, for isolating subjects and using selective focus. It has a rounded 9-blade diaphragm and a weather-sealed construction.
The optical design uses two aspherical elements and one SLD element to reduce spherical and chromatic aberrations. A Super Multi-Layer Coating suppresses flare and ghosting, for more contrast and color accuracy in strong lighting.
A stepping AF motor drives autofocus. It is quick, precise and near-silent, which suits both photo and video.
