A fast maximum aperture of f/2.8 throughout the zoom range, a manual focus clutch as well as Splash-proof, Dust-proof and Freeze-proof construction make it suitable for the most demanding professionals and enthusiasts. An “MSC” (movie and still compatible) AF lens drive system ensures fast and quiet auto-focusing – especially important when shooting HD movies. A seven blade circular aperture produces pleasing background defocusing effects.
