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.
