Product Details:
SSM (Super Sonic wave Motor) - A built-in lens motor for faster automatic focusing with high torque at low speed, quick start/stop response, and quiet, smooth operation.
ED (Extra-low Dispersion) Glass - Four precision ED Glass lenses correct chromatic aberrations and deliver visually accurate results even at full telephoto zoom extension.
Internal Focusing System - Internal lens elements move, so the overall length does not change creating a zoom lens that focuses more quickly and doesn?t affect the balance of your camera.
2 DMF (Direct Manual Focus) Modes - Allow you to quickly revert to manual focus by just turning the manual focus ring of the lens.
Versatile Focus Hold - Three focus hold buttons in different lens locations, plus electronic slider focus range selector switch.
