The Sigma 24-70mm f/2.8 IF EX DG HSM Lens is a large aperture standard zoom lens that covers a range from wide angle to short telephoto. It is ideal for general photography such as snapshots, portraiture and landscapes. When used on digital SLR cameras which use the APS-C (Sony DT) sensor, this lens will provide a focal length equivalent to 36-105mm in 35mm terms.
This lens was developed to fulfill the needs of serious photographers asking for hypersonic motor technology for fast focus response. Also included is the full-time manual over-ride allowing instant control in low-light situations. Whether you're shooting in fast paced situations or low light situations this lens can handle it.
DG is a designation that Sigma uses on lenses featuring optical systems designed to meet the performance characteristics of digital SLR cameras. The Super Multi Layer Coating reduces flare and ghosting, and the use of ELD and SLD glass provides excellent correction of all types of aberrations. The Hyper Sonic Motor (HSM) ensures a silent, high-speed AF function as well as full-time manual focusing capability.
