Sigma 24-70mm f/2.8 EX DG HSMPress Release:

The Sigma Corporation is pleased to announce the new 24-70mm F2.8 EX DG HSM. This large aperture standard zoom lens covers focal lengths from 24mm and is housed in a compact construction. The latest optical design provides an overall length of 94.7cm.

It is ideal for general photography such as portraiture and landscapes.  The Super Multi Layer Coating reduces flare and ghosting. ELD (Extraordinary Low Dispersion) glass, two SLD (Special Low Dispersion) glass elements and three aspherical lenses provide excellent correction of all types of aberrations. Superior optical performance is ensured throughout the entire zoom range.

This lens incorporates HSM (Hyper Sonic Motor), ensuring a quiet and high speed AF as well as full time manual focusing capability.  This lens has a minimum focusing distance of 38cm and a maximum magnification ratio of 1:5.3. The rounded 9 blades diaphragm creates an attractive blur.

It is possible to attach the included petal-type hood to block out extraneous light.
