versatility and mobility to rapidly respond to a wide range of shooting
situations, from portraits and snapshots to sports, this is a lens you
should consider. It features an extensive 11x zoom range, from wide
18mm to 200mm telephoto with impressive image quality all the way.
The advanced Optical SteadyShot image stabilization system included
in this lens will not only make it easier to shoot blur-free stills at long
focal lengths, but it also has an automatic Active Mode that will help
keep your movie images steady as you move around with the camera
while shooting at the wide end of the zoom range. Another feature
that contributes to high-quality movie production is extremely quiet
autofocus and aperture operation that will keep your soundtracks free
of unwanted camera noise.
