The Sigma Corporation are pleased to announce the launch of the new APO 50-150mm f/2.8 EX DC HSM II lens for Sony and Pentax digital SLRs.

This large aperture telephoto zoom lens is designed to match APS-C size image sensors and its compact, lightweight body provides freedom of movement and versatility.

As the overall length of the lens does not change during focusing and zooming, convenient handling is ensured. The HSM (Hyper Sonic Motor) system allows quiet and high-speed auto focusing with full time manual focus override by just rotating the focusing ring.

The addition of the optional 1.4x EX DG APO or 2x EX DG APO Tele Converters produce a 70-210mm f/4 AF tele-zoom lens and a 100-300mm f/5.6 AF ultra-telephoto zoom lens respectively.

It's announced as HSM for Sony and Pentax, with an asterisk on their website stating that it will not be AF if the caméra is not able to... Same here. Am I missing something about my Minoltas and A100? Is it meant for the next generation of alphas?
