Sigma's professional Art-series standard zoom for full-frame DSLRs with OS stabilisation.
The Sigma 24-70mm f/2.8 DG OS HSM Art launched in 2017 as Sigma's professional standard zoom for full-frame DSLRs. As an Art-series lens it delivered optical quality rivalling or exceeding first-party Canon and Nikon 24-70mm f/2.8 zooms while adding OS stabilisation that neither first-party version offered.
Optical quality is outstanding with excellent sharpness from wide open and well-controlled aberrations. OS provides approximately 4 stops of stabilisation. HSM motor is fast and quiet. Build is weather sealed with Art-series quality. The lens is calibratable via Sigma's USB Dock.
Available in Canon EF, Nikon F, and Sigma SA mounts. Filter thread is 82mm. The Sigma 24-70mm f/2.8 DG DN Art is the newer mirrorless version for Sony E and L-Mount. The DSLR version remains relevant for Canon and Nikon DSLR shooters.
Good value used. Check OS operation, HSM motor, and AF calibration (use Sigma USB Dock if possible). Some copies need fine-tuning for optimal AF. When properly calibrated this is one of the finest standard zooms available for DSLRs.
