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 lens offers a large aperture of f/2.8 and its large depth of field offers greater freedom of creative expression. It has a maximum aperture of f/2.8. Four SLD glass elements are used for maximum correction of chromatic aberrations.
