Versatile Zoom for Sony E-Mount

The Sigma 28-70mm f/2.8 DG DN Contemporary lens covers wide-angle to portrait focal lengths with a constant f/2.8 aperture. It is built for Sony full-frame E-mount cameras and suits photographers and filmmakers who need a bright, compact zoom for everyday shooting. The kit adds a 67mm filter set, hood, pouch and cleaning accessories.

Constant Aperture and Filter Size

The f/2.8 maximum aperture stays fixed across the 28-70mm range, giving consistent exposure when zooming. The lens accepts 67mm front filters, which matches the included UV, CPL and FLD filters. Minimum aperture is f/22. The stepping motor provides quiet AF, though the lens has no built-in stabilisation and relies on the camera body for shake reduction.

28mm Wide End Defines Use

The zoom starts at 28mm rather than 24mm, so interiors and expansive landscapes may feel tight compared with wider zooms. Buyers who need that extra wide coverage should look elsewhere. For portrait, street and general-purpose work the 28-70mm range with constant f/2.8 remains a strong, lightweight choice.

Questions about this item

Should I choose the lens kit with the 67 mm filter set or buy the lens alone?

The listed kit bundles the Sigma 28-70 mm f/2.8 DG DN Contemporary lens with a 67 mm UV filter, circular polariser, FLD filter, tulip hood, pouch, blower, cleaning pen, cloth, starter cleaning kit and cap keeper. Buying the kit supplies all protection and cleaning accessories in one box.

What does the constant f/2.8 aperture mean when I am shooting with this lens?

The maximum aperture stays at f/2.8 from 28 mm through 70 mm, so exposure settings do not shift while zooming and you retain the same depth-of-field control across the entire range.

Does the Sony E mount limit the aperture or autofocus speed in any way?

The lens is built for full-frame Sony E mount and communicates natively with the camera body, so the f/2.8 to f/22 aperture range and the stepping motor AF operate without adapter restrictions.
