Canon CN7x17 KAS T/R Cine-Servo 17-120mm T2.95-3.9 Lens (Canon RF)

The Canon CN7x17 KAS T/R Cine-Servo 17-120mm T2.95-3.9 Lens (Canon RF) 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 with a native RF mount for use on cinema cameras such as the EOS C400 and covers sensors up to Super35, and it is suitable for 8K/4K acquisition.

Quick Features

Versatile 17-120mm focal length with 7x zoom ratio
Supports 8K/4K cameras such as EOS C400
Detachable next-generation eX-s V servo drive unit
Supports virtual production with ZEISS eXtended data and Cooke /i technology
11-blade iris for soft bokeh
127mm filter diameter on hood; 112mm diameter on lens
114mm front diameter
Supports ARIA (Automatic Restoration of Illumination Attenuation) with compatible cameras

Versatile Optical Performance

This servo zoom lens is designed with a consistently warm color balance that reproduces skin tones and works with HDR video. The 11-blade iris offers a natural, circular bokeh from fully open to minimum aperture. The odd number of iris blades produces a soft and diffused light beam when shooting bright subjects.

Support for 8K/4K Cameras

Canon's optical technology uses large-diameter aspherical lenses and anomalous dispersion glass to deliver optical performance that supports 4K and 8K cameras throughout the zoom range. Aberrations are controlled from edge to edge for clean image performance.

Next-Generation e-Xs V Servo Drive Unit

The next-generation servo e-Xs V drive unit on this lens has the same operability and usability as ENG lenses, adding faster focus and iris speed, Focus Breathing Compensation, and a USB-C connector. The USB-C port allows drive unit settings to be saved and loaded into other lenses. Also, users can record and save maintenance history. Three 20-pin connectors below the servo housing allow many Canon and third-party zoom, focus, and iris controllers to be connected. The drive unit can also be detached to be used in manual-style cinema configurations.

Remote and Virtual Support

The high-resolution, 16-bit absolute-value encoder enables high-precision location detection, making calibration easier when creating virtual content. The 20-pin connector can be switched to a virtual terminal to output zoom, focus, and iris position information.
This lens also supports RF-mount communication, which provides distortion and shading data for virtual production with compatible cameras. In addition to RF mount communication, 12-pin serial communication for standard broadcast camera systems is available.

Supports AF Functions

This RF-mount lens supports Dual-Pixel CMOS AF II with an expanded distance measuring area to significantly reduce focus problems in 4K shooting. This function can be used when combined with compatible cameras such as the EOS C400.
