    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.
