    They delivered the 300 with the extra Sync-IS.
    .
    If they can duplicate the acclaimed sharpness and IS that tests and users of the 300mm Zuiko are praising this will be a very interesting lens.
    .
    For me, the 500mm would be to RENT as I rarely need such a lens 🙂 1000mm in Full Marketing Frame terms. Interesting find!
