Canon Cine-Servo 17-120mm T2.95 Overview
The Cine-Servo 17-120mm T2.95 with EF mount from Canon is designed to combine the functionality and form factor of a broadcast, ENG-style motorized zoom lens with the optical precision of a cinema zoom. The lens is designed for use on cinema cameras with sensors up to Super 35mm (26.2 x 13.8mm) in size and is suitable for 4K acquisition. With a detachable drive mechanism and support for rod attachment, it is designed to be equally at home whether being used by a solo camera operator or a full production team.
With a 17 to 120mm focal length, the lens features 7x zoom and has a maximum aperture of T 2.95 when set to 91mm or wider. Additionally, it features an 11 blade iris to create circular bokeh patterns as well as to reduce refraction. For ENG-style shooters the lens drive features servo motors powering zoom, focus, and iris. The lens can be connected to the camera either using a standard 12-pin connector or will communicate directly through the lens mount when attached to compatible cameras. Three 20-pin connectors below the servo housing allow many Canon and third-party zoom, focus, and iris controllers to be connected.

Easier-to-Read Ring Markings
The lens incorporates the following features designed to make the markings easier to read:
- The focus ring markings are placed on an angled surface so that they can be seen even by an operator sitting behind the camera
- Each ring marking is printed on both sides of a lens allowing focus-pullers or camera assistants to operate the lens from various positions. Additionally, the markings on one side of the lens have a luminous coating so that they can be read even in the dark
- The focus ring features both metric and imperial scales (meters and feet) so that you do not have to replace the lens ring to suit users accustomed to different units of measure

Lens-to-Camera Metadata Transmission
The lens communicates directly with Cinema EOS camera through the lens interface. This allows lens metadata such as zoom setting and iris to recorded in the camera. Note that a firmware update may be required for proper communications between the lens and the camera.
In addition the lens features a standard 12-pin broadcast camera interface and can also transmit zoom, focus, and iris data to a camera or other device via this connection
