Product description
Announced Feb 8, 2011

The Sigma 12-24mm F4.5-5.6 II DG HSM is an updated version of its ultra-wideangle zoom for full frame SLRs. It uses a revised optical formula which incorporates no fewer than four elements made from its latest 'F' low dispersion glass, plus one SLD element, to minimise chromatic aberration. Four aspheric elements (three glass mold and one hybrid) are also employed to reduce distortion and other aberrations. Covering an 18-36mm equivalent range on APS-C digital cameras, the 12-24mm features a HSM focus motor for fast and silent AF, with full-time manual focus override. At its closest focussing distance the 12-24mm provides a maximum reproduction ratio of 1:6.4 - not true macro, but usefully close nonetheless. A built-in lenshood protects the front element, and spash-proof construction should keep the lens safe in moderately poor weather.
