Compact f/2.8 zoom for mirrorless
The SIGMA 28-70mm f/2.8 DG DN Contemporary is built exclusively for mirrorless cameras and covers full-frame sensors. Its constant f/2.8 aperture runs from 28mm to 70mm, giving photographers a versatile standard zoom in a lightweight body designed for daily carry. The lens suits creators who want professional optical quality without the bulk of larger Art-series zooms.
Optical limits of the constant aperture
The f/2.8 maximum aperture stays fixed across the zoom range, so exposure settings remain consistent while framing changes. The design uses 16 elements in 12 groups, including specialised low-dispersion and aspherical glass, to control aberrations at the wide end and maintain edge-to-edge sharpness at 70mm. Internal focusing keeps the barrel length constant, which helps when using polarising filters or lens hoods.
Mount and clearance checks before ordering
Confirm your camera uses a compatible mirrorless mount that supports lens-based optical correction and high-speed autofocus with a stepping motor. The front element carries a water- and oil-repellent coating, so verify filter-thread size if you plan to add protective or creative filters. Ensure the tripod’s 235mm folded length fits your bag and that the accessory kit contents match your workflow needs.

Questions about this item
How do the 28mm and 24mm wide ends compare for everyday shooting?
The 28mm start makes this lens smaller and lighter than a 24-70mm while keeping the same f/2.8 constant aperture, so you trade a touch of wide angle for noticeably easier carry.
What does the constant f/2.8 aperture deliver across the 28-70mm range?
You get the same bright f/2.8 at every focal length, enabling consistent exposure, shallow depth of field and reliable low-light performance whether you are at 28mm or 70mm.
How does the stepping motor work with mirrorless autofocus systems?
The built-in stepping motor drives fast, quiet internal focusing that pairs with high-speed mirrorless AF and supports lens-based optical corrections for sharper results.
