A powered zoom lens that has been created to satisfy professional optical and operational requirements for high-quality movie imagery, including 4K, when matched with a 35mm full frame format camera such as the A7S or a Super 35 format camcorder such as the PXW-FS7. Focus breathing and zoom image shift have been reduced to an absolute minimum, while aspherical elements and advanced multi-coating technology effectively suppress aberration. Quiet operation is also a priority, so an SSM (Super Sonic wave Motor) drive system has been employed for precise, quiet zooming. Independent control rings for zoom, focus, and iris using physical stops are provided for the first time into an E-Mount an lens. Built-in Optical SteadyShot image stabilization adds to the extraordinary performance of this outstanding lens which is supporting a constant F4.
