The Sigma 28-70mm F2.8 DG DN Contemporary Lens with a Sony E-Mount redefines the standard zoom for mirrorless cameras by
combining outstanding optical performance, an F2.8 constant aperture, and a lightweight and compact body. The
design of the 28-70mm F2.8 DG DN Contemporary is based on the existing 24-70mm F2.8 DG DN Art, but
with a focal range starting at 28mm, making the lens body significantly smaller and lighter while maintaining
superb optical performance.
