The Canon CN7x17 KAS T/R1 is the RF-mount version of Canon's CINE-SERVO 17-120mm with the e-Xs V digital drive unit, and the first CINE-SERVO lens with an RF mount. It's a 7x zoom from 17 to 120mm with a 31.4 mm image circle, and it supports 8K cameras with consistent colour balance and reduced focus breathing.

7x zoom range

The zoom runs 17-120mm at T2.95 from 17 to 91mm and T3.9 at 120mm, with no built-in extender. Minimum focus is 0.85 m, the iris has 11 blades and the front diameter is 114 mm.

e-Xs V digital drive unit

This is the first CINE-SERVO to come with Canon's e-Xs V digital drive unit. Focus and iris are faster than on earlier models, for fast-moving subjects such as sport, and the servo control includes optical focus breathing correction. Three 20-pin connectors and a USB-C port allow remote control and user settings, and a 16-bit encoder outputs precise lens data for virtual production. An information display sits on top of the drive unit, where the camera operator can see it. The drive unit can be removed for manual, cinema-style operation.

RF mount communication

With supported cameras, the RF mount offers lens distortion correction and real-time metadata capture, and its data includes distortion and shading correction for virtual production and VFX workflows. 12-pin serial communication is also available with broadcast camera systems that support it. The RF version is approximately 286.9 mm long and weighs approximately 3.11 kg.
