Overview

The Sigma 24-70mm f/2.8 EX DG HSM is a budget-friendly standard zoom offering good stopped-down sharpness and solid build, but exhibits significant corner softness wide open, especially on full-frame. It features HSM autofocus, a satin finish, and compact size compared to rivals. The lens lacks optical stabilization and weather sealing, and has a loud AF motor. It suits budget-conscious photographers needing a fast-aperture zoom for general use, particularly on APS-C bodies where corner issues are less pronounced.
