The Sigma 56mm F1.4 DC DN Contemporary is a prime lens for Sony E mount. It is compact and lightweight, and it belongs to Sigma's Contemporary line. The f/1.4 maximum aperture gives a bright image and a soft bokeh effect, even at a mid-telephoto focal length.
On an APS-C Sony E body, the field of view is equivalent to 84mm in 35mm terms. The aperture range is f/1.4 to f/16. The optical design uses one SLD element and two aspherical elements, with Super Multi-Layer Coating and a rounded 9-blade diaphragm. The construction is weather-sealed.
A stepping motor autofocus system keeps focusing smooth and quiet, which suits video shooting. The lens works with Sony E mount Fast Hybrid AF for precise tracking. With the camera's face recognition or eye AF, focus stays on the face or eye when the subject moves.
