The Fujinon XK20-120mm T3.5 Cabrio Lens is the lens only and does not include the servo zoom unit, which you can source separately. It is a wide-to-telephoto zoom lens for Super35 cameras and features a PL mount. The focus, zoom, and iris barrels are geared with standard 0.8 Mod gears, which provides an interface for the optional ENG-style digital drive unit. The rear PL mount features electrical contacts for sharing ARRI LDS and Cooke /i Technology lens data with the camera; however, you need the optional digital drive unit to activate these contacts. An included rectangular lens hood provides flare protection and is useful for run-and-gun or ENG-style shooting. A removable lens support is included with the lens.
