    24–70mm · f/2.8

    Overview

    The Sigma 24-70mm f/2.8 EX DG Macro is a well-built, affordable alternative to Canon's L lens, costing less than half the price. Optically, it is very sharp at wide angles but performance degrades at longer focal lengths, with 70mm f/2.8 considered unusable. Distortions, CA, and vignetting are moderate. Build quality is fine, though it suffers from zoom creep and a loud AF motor. The lens offers macro capability at 1:3.8 magnification. It suits budget-conscious photographers needing a fast standard zoom, especially for wide-angle use.
