A constant f/2.8 standard zoom for Sony E-mount full-frame mirrorless bodies, built as a smaller, lighter alternative to Sigma's 24-70mm f/2.8 DG DN Art. It trades the 24mm wide end for a body that is easy to carry all day, while keeping the fast aperture that makes it usable indoors and in low light. It suits event, portrait and travel shooters who want one lens that covers most situations. Against rivals like the Sony 24-70mm f/2.8 GM and the Sigma Art, it gives up some wide-angle reach and edge sharpness wide open in exchange for portability.

Owners and reviewers treat it as the value pick among fast full-frame standard zooms: sharp in the center, light enough to carry all day, and quick to focus. Most complaints center on the 28mm wide end and softer corners at f/2.8.
The Sigma 28-70mm F2.8 DG DN Contemporary is a standard zoom lens for full-frame Sony E-mount mirrorless cameras. It has an F2.8 constant aperture and a focal range of 28mm to 70mm.
Its design is based on the Sigma 24-70mm F2.8 DG DN Art, but the focal range starts at 28mm. This makes the lens body significantly smaller and lighter while keeping the optical performance. It is the smallest and lightest lens in its class.
As part of Sigma's Contemporary line, it balances optical performance with lens size. Sigma's optical engineers added a new combination of coatings and structural elements for use in a wide range of shooting environments. Newer production and manufacturing techniques were used to achieve high build quality.
