Broadcast Standard Interface. The lens features the same 12-pin camera interface for power and serial data as found on regular Canon broadcast lenses.

Motorized Zoom. This lens features an ENG-style hand grip with a zoom rocker. Power is provided by a 12-pin Hirose connector (we provide a D-Tap adapter).

Cinema Construction. Designed with professional production needs in top priority, the lens has dual film industry pitch gears (0.8 & 0.5) for focus, zoom, and iris control, an 11-blade stepless aperture, and a built-in 3/8"-16 threaded mount for attaching the included Wooden Camera 15mm Universal Lens Support. For an updated version of this lens with improved focus and iris speeds, check out the Canon Cine-Servo 17-120mm T2.95-3.9 PL e-Xs V Servo Drive.

Super 35 Sensor Coverage. The Canon 17-120mm T2.95-3.9 is designed specifically for image sensors measuring 26.2 × 13.8mm and smaller. That makes it perfect for Super 35mm/APS-C crop-sensor cameras, offering a focal length roughly equivalent to 27-192mm.
