Sony's 28-135mm is a compact powered zoom-lens. It 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 α7S or a Super 35 format camcorder such as the 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 lens. Built-in Optical SteadyShot image stabilization adds to the extraordinary performance of this great lens, which is a constant F4.
