Sigma's full-frame 24-70mm f/2.8 workhorse for Nikon shooters.

The 24-70mm f/2.8 range is where a lot of professional work actually gets done, and Sigma built this lens to compete directly in that space. The constant f/2.8 aperture holds across the entire zoom range, so you're not scrambling to compensate for exposure shifts as you zoom through a reception or a press conference. HSM (Hyper Sonic Motor) autofocus keeps up with moving subjects without stealing light or time, and the internal focusing design means the front element stays put, useful when you're shooting with polarizers on that 82mm thread.

The DG designation confirms full-frame coverage, so this lens works across the Nikon F ecosystem from crop bodies up through full-frame DSLRs like the D800 or D4 series. EX-grade construction reflects Sigma's higher-tier build standard, with the kind of physical durability that holds up across extended shooting schedules. For photographers who want a single zoom to carry through a long day without swapping glass, this focal range covers wide environmental shots at 24mm and tighter portraits at 70mm, all at the same fast aperture.

Who It's For

Wedding photographers working reception halls will lean on that constant f/2.8 when venue lighting drops and there's no option to add flash. Event and documentary shooters get a focal range that covers crowd-wide context and individual moments without reaching for a second body. Portrait photographers working on location can use the 70mm end at f/2.8 for subject separation without hauling a prime. Photographers already invested in Nikon F glass get full-frame compatibility and HSM autofocus in a zoom that fills the gap between a wide prime and a short telephoto.

FAQ

Does this lens maintain f/2.8 across the entire 24-70mm range?
Yes. The constant f/2.8 aperture holds from 24mm through 70mm, so exposure and depth of field stay consistent as you zoom.
What's HSM autofocus, and why does it matter?
HSM (Hyper Sonic Motor) is Sigma's fast autofocus system that doesn't steal light from the imaging plane - important for fast, accurate AF during events or fast-moving subjects.
Will the front element rotate when focusing?
No. The IF (Internal Focus) design keeps the front element stationary, so you can use polarizers or other front-mounted filters without rotation issues.
Is this lens compatible with Nikon crop-sensor bodies like the D7000 or D500?
Yes. The DG designation means full-frame coverage, but the lens works on any Nikon F-mount body, including crop sensors. On crop bodies, the effective range becomes roughly 36-105mm.
What's the filter thread size?
82mm. That's a larger thread than entry-level zooms, but standard for pro-level glass in this focal range.
What does the EX designation mean?
EX reflects Sigma's higher-tier build standard - more robust construction and optical quality designed to withstand heavy professional use.
