Sigma 10-20mm F/4-5.6 EX DC HSM

With a glance across the spec sheet, the Sigma 10-20mm f/4-5.6 could almost be mistaken for the f/3.5 version. It has the same focal range and features Sigma’s Hyper Sonic Motor providing fast and reasonably quiet autofocus as well as functionality on Nikon bodies lacking their own AF motor. Like its cousin, we found the AF to be fairly responsive with only a slight delay while it brought the subject into sharp focus. It was fairly quiet too. As you’d expect, this lens is smaller than its ‘fast’ cousin and weighs in at 470g, keeping it well balanced on smaller D-SLRs, but it features the same build quality, with a similarly fluid motion to the focus and zoom rings. Costing £399 it certainly offers a good option and really only lags behind the f/3.5 version in the all-important image quality stakes.

Verdict

With an RRP of £399 Sigma's variable aperture 10-20mm certainly offers a good option and really only lags behind the f/3.5 version in the all-important image quality stakes.
