Sigma 24-70mm f2.8 IF EX DG HSM Sony mount lens review: Good performer

As an moderately priced full-frame high-speed standard zoom, the Sigma 24-70mm f2.8 seems like a promising option to the far pricier offerings from the camera makers. Read on to find out how well it performs.

As a standard zoom the Sigma 24-70mm f2.8 IF EX DG HSM is ideal for general-purpose photography including portraiture, candid, landscape and reportage.  Introduced in 2008, it boasts an impressive spec to rival any of the big-name brands. The optical construction consists of 14 elements arranged in 12 groups and, as you would expect from Sigma, it adopts aspherical elements, as well as liberal use of low-dispersion glass for reducing the effects of chromatic aberration.

It also features a quiet sonic type AF motor focusing to a minimum distance of 15” (38cm) as well as rounded diaphragm opening for softer transitions to out of focus area. With an 82mm filter thread and 3.5” (89mm) maximum diameter it’s not exactly a small lens but it is shorter than average, measuring 3.7” (94.7mm) in length and weighs in at 27.9 oz (790g).
