Digital Camera World Verdict

Sigma has created a beautifully engineered standard zoom with the 24-70mm f/2.8 DG OS HSM | A, which more than earns its “Art” moniker. Image quality is simply superb, with excellent sharpness, high contrast and gorgeous bokeh, and there are also useful autofocus options, including a manual override for quickly taking direct control. A four-stop optical stabiliser rounds out a hugely impressive package, and makes this lens a quality choice for practically any photographer.

Pros

Sigma’s ‘Art’ line lenses have earned excellent reputations, although most are wide-angle primes and zooms. This is Sigma’s first 24-70mm zoom in the Art category. As such it’s a direct competitor not only to Canon’s older 24-70mm f/2.8 lens, but also to the Tamron SP 24-70mm f/2.8 Di VC USD G2 lens. So how does this standard zoom stack up compared to its competition? We put the Canon-fit version through its paces to find out.

Although it’s not a fully weather-sealed lens, the Sigma has a rubber seal on its mounting plate and the overall construction feels fabulous, based on a sturdy metal barrel and brass mounting plate. Zoom and focus rings are smooth in operation, and the ring-type ultrasonic autofocus system is speedy and accurate. Autofocus comes with switchable options for regular manual override, plus manual-priority autofocus. With the latter, manual override works without the need to wait for AF to lock onto a subject, as well as being available in AI Servo mode.
