    This versatile 10x high zoom ratio lens designed specifically for the digital imaging and it covers the wide range of the focal lengths. This lens uses SLD (Special Low Dispersion) glass for correction of color aberration, and seven-group zoom system provides a high magnification throughout the entire zoom range. Super multi coating reduces flare and ghost. The HSM (Hyper Sonic Motor) system provides quiet high-speed auto-focus shooting, as well as full-time manual focus.

    Re: Sigma APO 50-500mm F4-6.3 EX DG HSM for Four Thirds Mount Lens - Press Release

    Has anyone heard of a release date for this lens or possibly seen one anywhere?

    I emailed Sigma directly about a month ago and was told that there was, as of that time, no release date scheduled.

    Just hoping to expand my lens selection with a decent super telephoto in the casual users price range.
