The Sigma 24-70mm f/2.8 EX DG Lens is a well-built, well-spec’d lens with a decent price . It does not outperform (physically or optically) Canon’s similarly spec’d EF 24-70mm f/2.8 L USM Lens, but it costs less than half as much.
Is the 24-70mm EX-DG DF worth it?
The 24-70mm f/2.8 EX DG DF is a truly amazing lens. My copy was bought used, in pristine condition. It is not the HSM autofocus, it uses the ‘screwdriver’ focusing mechanism. It is extremely fast to focus, all the way from closest focus to infinity. A word about ‘noisy’ focus this lens is blamed for.

The Sigma 24-70mm ƒ/2.8 HSM takes about 1 second to focus from infinity to close-focus, about average for a lens of this type. It focuses nearly silently and short focus throws happen very quickly.
