Sigma's 12-24mm f/4.5-5.6 DG HSM II Lens (For Sony) is designed for use with full-frame digital cameras, and offers a dramatically ultra-wide, minimally distorted zoom lens with a field of view from 122 to 84.1. This range makes it ideal for the tightest of interiors, as well as for dramatic landscape photography. Using a camera with an APS-C sensor will give you an effective range of 17-35mm, also a very attractive wide-angle zoom range.
