The Sigma 35mm F1.4 DG DN | Art is a full-frame, fixed 35mm lens for Sony E-mount mirrorless cameras. It was redesigned for mirrorless cameras and is smaller and lighter than Sigma's earlier 35mm F1.4. It is built at Sigma's factory in Aizu, Japan.
The optical design has 15 elements in 11 groups. These include two SLD elements, one ELD element, one FLD element and two aspherical elements, which are used to reduce aberrations. The 11 rounded diaphragm blades give round out-of-focus highlights. Anti-ghosting and anti-flare technology helps keep contrast in backlit conditions.
Autofocus uses a stepping motor that drives a single lightweight focusing element, so focusing is quiet. Manual focus is also available. The barrel has an aperture ring that can be de-clicked and locked in Auto, a focus mode switch and an AFL button that can be customized in the camera menu, depending on the model. The body is dust and splash proof, and the front element has a water and oil repellent coating.
