Sigma 28-70mm f/2.8 DG DN Contemporary Lens (Sony E)

A versatile standard zoom for mirrorless cameras, the Sigma 28-70mm f/2.8 DG DN Contemporary delivers a constant f/2.8 aperture for shooting in low light and controlling depth of field. Its compact, lightweight design—featuring two FLD and two SLD low-dispersion elements plus three aspherical elements—minimizes aberrations for sharp, clear imagery with accurate color reproduction. The single lightweight focusing element and stepping motor enable fast, silent autofocus, making it ideal for filmmakers and content creators. Super Multi-Layer and Nano Porous coatings reduce flare and ghosting while maximizing contrast and light transmission. A water and oil-repellent front coating protects against smudges, while rubber sealing provides dust and splash resistance. The nine-blade rounded diaphragm produces beautiful bokeh at wider apertures, and the brass bayonet ensures mounting precision and rigidity.

Each optical surface features Super Multi-Layer and Nano Porous coatings to improve contrast and color rendering by suppressing lens flare and ghosting for optimal light transmission, and an added water- and oil-repellent coating on the front optic helps keep the lens free from smudges and droplets. The weather-sealed design benefits working in trying environmental conditions, and a nine-blade rounded diaphragm contributes a pleasing bokeh quality when using wider apertures.
