Versatile Art Zoom for Sony E

The SIGMA 28-105mm f/2.8 DG DN Art is a full-frame zoom lens built for Sony E-mount mirrorless cameras. It covers a broad 28-105mm range with a constant f/2.8 aperture, making it a single-lens solution for wide-angle, standard and short-telephoto work. The Art designation signals high optical performance across the frame.

Suited for hybrid shooters needing constant aperture

Photographers and videographers who want one lens for landscapes, events and portraits will benefit from the fixed f/2.8 brightness and 12-blade diaphragm. The HLA autofocus motor delivers fast, quiet focusing for both stills and video. Buyers who need wider than 28mm, longer reach than 105mm, or a lighter variable-aperture zoom should consider other options.

Constant f/2.8 aperture through the zoom range

The defining specification is the f/2.8 maximum aperture that does not change from 28mm to 105mm. This preserves exposure settings while zooming, aids low-light performance and enables consistent depth-of-field control. If your workflow demands a fixed aperture across a wide-to-telephoto range, this lens meets that requirement.

Questions about this item

Will this 28-105mm f/2.8 Art lens work on my Sony APS-C body and what focal lengths does it cover?

The lens mounts on Sony E-mount cameras; on APS-C bodies the 28-105mm zoom provides a wider field of view while maintaining the constant f/2.8 aperture across the range.

How can I verify the HLA autofocus and constant f/2.8 aperture are performing correctly after setup?

Focus on a subject at 28mm and 105mm — the HLA motor should lock quickly and silently at both ends, and exposure should stay consistent when zooming because the aperture remains f/2.8 throughout.

Does the box include the lens hood, caps and case, or must I buy them separately?

The lens ships with a hood, front and rear caps, and a protective case; no additional accessories are required for basic operation.
