Sigma 28-70mm f/2.8 DG DN – Sony E

Meet your new go-everywhere zoom. The Sigma 28-70mm f/2.8 DG DN Contemporary for Sony E-mount redefines what a constant-aperture zoom can be — delivering f/2.8 light-gathering power in a body that's noticeably lighter and more compact than competing 24-70mm alternatives.

Optical Excellence from Edge to Edge

Inside, two FLD and two SLD low-dispersion elements work alongside three aspherical elements to tame chromatic aberration, color fringing, spherical distortion, and more. Every optical surface carries both Super Multi-Layer and Nano Porous coatings to crush flare and ghosting, while a water- and oil-repellent front coating keeps smudges and rain droplets from slowing you down. The result is imagery that's sharp, color-accurate, and high in contrast — whether you're shooting wide open or stopped down.

Built for Hybrid Shooters and Demanding Conditions

A single lightweight focusing element paired with a fast, quiet stepping motor delivers autofocus that's near-silent and highly responsive — perfect for video creators running a gimbal rig. The rubber-sealed, dust- and splash-resistant construction handles tough environments with confidence, and a nine-blade rounded diaphragm renders out-of-focus backgrounds with beautifully smooth bokeh. A brass bayonet mount ensures precise, rigid attachment every time you click it onto your camera.
