This is a stabilized telephoto ENG style lens for large venues or sporting events. Its RS-232 port allows remote control for full servo studio control, robotics, jibs, tower cams, teleconferencing and other applications where remote control of zoom, focus and iris via RS-232 serial data or traditional analog control is desired.

Remote control of the 2X extender is possible with the optional model ECU-2A remote extender module.
