How does the optical image stabilizer in the Panasonic Lumix DMC-FZ1 work?

  1. How does the optical image stabilizer in the Panasonic Lumix
    DMC-FZ1 work? Has anybody taken it apart or found any
    information from the manufacturer? I'd be curious.

    The lens is actually made by the German company Leica.

    By the way, I've tested the lens and found that at max zoom and
    low to medium light the image stabilizer is not good enough to
    yield sharp pictures handheld, but that's actually to be
    expected at an equivalent of 420 mm focal length.

    When held steady enough, the lens yields almost perfectly sharp
    pictures even at max zoom and fully open aperture (1 : 2.8) on
    the admittedly not too demanding 2 Megapixel sensor..

    Ian,

    interesting! Thanks for the info.

    But now back to the original question. How does the image
    stabilizer actually work? Does it shift a lens group around
    mechanically? If so, how are the lenses moved? Where does the
    force come from? Is it just some kind of clever pendulum
    mechanics or is it electronically controlled like the Canon IS
    lenses?
