The 24-105mm F4 DG OS HSM is a relatively wide-range standard zoom for full frame SLRs, and part of Sigma's line of high quality 'Art' lenses. It offers a useful wide angle to moderate telephoto zoom range, and includes a Hypersonic Motor for fast, silent focus. Optical Stabilisation is also available to combat camera shake. The lens can also be used on APS-C / DX format cameras, on which it will offer a 36-160mm equivalent angle of view. The Sony mount version does not have optical stabilization, as Sony's Alpha DSLRs provide in-camera stabilization.
