The Sigma 56mm f/1.4 DC DN Contemporary is a mid-telephoto prime lens for Sony E-mount cameras. Its f/1.4 aperture gives a bright image and a good amount of background blur, even on APS-C cameras. It is the third lens in Sigma's f/1.4 series, after the 30mm and 16mm.
The lens is compact and lightweight. Its optical design relies on the camera body to correct peripheral light falloff and distortion. An SLD glass element corrects axial color aberration. It suits subjects from portraits and snapshots to night views.
A stepping motor and an optical design made for video AF give smooth, quiet autofocus. The lens works with Sony E-mount Fast Hybrid AF for precise tracking. With face recognition or eye AF on the camera, focus stays on the face or eye as the subject moves.
