Detailed Features

High performance, highly versatile

Using our rich heritage of optical expertise, Canon has created a lens offering outstanding quality -from image centre to image edge. The CN7x17 KAS S E1/P1 supports 4K resolution and incorporates an 11-blade diaphragm to deliver softer, more attractive out of focus areas.

Thanks to an impressive 7x zoom, with focal length spanning 17mm to 120 mm, and maximum T-number of T2.95, the CN7x17 KAS S E1/P1 may be the only lens you need. A 3-group inner focus system developed for Canon lenses reduces focus breathing to an absolute minimum.

It is both weatherproof and shockproof – durable enough for every shooting environment.

Designed for broadcast shooting styles

The CN7x17 KAS S E1/P1 employs a servo drive unit, enabling use in broadcast-style shooting environments where cine lenses are impractical. Compact and lightweight, it offers comfortable on-the-shoulder shooting with the familiar feel of a typical TV zoom lens. Focus ring rotation is 180°, balancing the accuracy required for 4K imaging with the speed needed for broadcast use. High resolution encoders mean that actions are precisely repeatable, whilst fast start-up and high-speed operation ensure you never miss a moment.

For tripod-based set-ups, existing Canon demand units can be used to control zoom, focus and iris. Virtual studio use is also supported thanks to a sophisticated 16-bit encoder output.

Perfect movie shoots

This lens is also ideal for movie shooting. With the drive unit removed, it can be operated like a traditional cine lens. Industry-standard accessories such as follow focus units are easily attached - 0.8 and 0.5 pitch gears are incorporated into the focus ring. Re-installation of the drive unit is simple. No adjustment of gear positions is required, enabling a fluid, versatile shooting style previously unavailable with large sensor cameras.

All Cinema EOS lenses are colour-matched, ensuring easy integration with other Canon cine lenses.

Camera/Lens communication


The CN7x17 KAS S E1/P1 supports multiple lens communication methods for added versatility. Canon’s EF-mount supports lens metadata and other functions such as Peripheral Illumination Correction. A 12-pin serial connection provides an interface found in broadcast environments. Cooke /i Technology is supported in the PL-mount variant, allowing capture of lens data by cameras often used in movie shooting environments.
