Versatile f/2.8 zoom for Sony E mirrorless
This Sigma Art lens covers 24-70mm on full-frame Sony E mirrorless cameras. The constant f/2.8 aperture delivers shallow depth of field and consistent exposure across the range. It suits photographers who need one lens for portraits, events and landscapes.
f/2.8 aperture limits low-light reach
The maximum aperture of f/2.8 performs best in moderate-to-bright light or overcast outdoor conditions. In dim interiors or at night the fixed aperture may require higher ISO or slower shutter speeds. The minimum focus distance of 6.7 inches also restricts extreme close-up work.
Replaces variable-aperture kit zooms
Stepping up from a slower variable-aperture zoom gains constant f/2.8 brightness and Art-series optical corrections. The upgrade is worth it when consistent depth-of-field control and corner-to-corner sharpness matter more than maximum telephoto reach. Buyers needing longer than 70mm or wider than 24mm will need additional lenses.

Questions about this item
Should I choose the 24-70mm f/2.8 or a different focal range for full-frame Sony E?
The 24-70mm f/2.8 covers wide to short telephoto with a constant f/2.8 aperture, ideal for events, portraits and landscapes on full-frame Sony E bodies.
What does the constant f/2.8 aperture mean when shooting indoors or at dusk?
A constant f/2.8 lets you keep the same exposure across the 24-70mm zoom range, giving shallow depth of field and usable shutter speeds in moderate-to-bright light or overcast conditions.
How does the 82mm filter thread affect the filters I can use?
The lens takes 82mm screw-in filters, so circular polarisers, ND filters and protective glass must match that thread size.
