New 50-150mm f/2.8 at Sigma

Sigma APO 50-150mm F2.8 EX DC HSMYet another new lens with a wide aperture: This time it is a zoom, APO 50-150mm F2.8 EX DC HSM. A long variation (from the standard 50mm to a small tele-lens 150mm). Nothing wrong in this zoom incorporating also an HSM (Hyper Sonic Motor) to allow quiet and high-speed auto focusing with full time manual focus override; Or maybe the fact that it should not be used with full-frame sensors, 35mm analog cameras, and other sensors of larger size than the common APS-C format (risk of significant vignetting).

The lens is fully compatible with the 1.4x EX DG APO or 2x EX DG APO Sigma tele converters.

Immediately available for Sigma AF, Canon EOS, Nikon AF, Sony and Pentax AF.
