Ultra-telephoto DG OS HSM lens

Sigma has announced the launch of the APO 150-500mm F5-6.3 DG OS HSM lens. The new lens is aimed at sports and wildlife photographers, and offers an equivalent focal range of 225-750mm in 35mm terms.

The 150-500mm is designed for APS-C sized image sensors, and features Sigma’s original OS image stabilisation. Other technology contained within the lens includes three SLD (Special Low Dispersion) glass elements for chromatic abberation correction, HSM (Hyper Sonic Motor) for fast and quiet auto focus.

A removable tripod socket is included with the lens as a standard component, while a range of tele-convertors are available to increase the focal range if needed

The 150-500mm is available for Sony and Pentax mounts, though there is no word yet on pricing.
