4K Optical Performance and HDR Imaging Quality
HDR images offer excellent gradation representation and enhanced realism and dimension, including texture, for image representation close to the real thing.
Canon's 4K UHDxs lenses deliver the advanced optical performance that Canon considers essential for a 4K+HDR system lens, helping to enable shooting of more realistic and immersive images.
Outstanding Optical Performance Designed for 4K+HDR Shooting


UHDxs Lenses Deliver Canon's Highest Optical Performance
UHDxs lenses provide our highest optical performance as they exhibit higher sharpness and lower chromatic aberrations relative to other broadcast lenses.

BT.2020 and HDR/WCG Support
The portable CJ20ex5B lens features correction data that supports BT.2020, which offers a wider color gamut than the conventional BT.709 broadcasting standard. This enables excellent color reproduction from edge-to-edge when attached to a 4K camera. Like the other UHDxs series lenses, the CJ20ex5B provides optimized chromatic aberration correction based on BT.2020 correction data, helping to enable more lifelike high-resolution video shooting with outstanding tonality and realistic texture and depth.
① BT.2020 (4K/8K Broadcast)
② BT.709


Compact, Lightweight and Ergonomic Design
Despite its impressive 5.0-100mm focal range, the lens weighs in at only 5.07 lbs. The portable CJ20ex5B 4K UHDxs lens is similar in size to Canon's other 2/3" HD lenses, while delivering 4K UHD performance and offering the mobility demanded in the reporting and documentary fields.
The lens grip allows the center of gravity to be close to the mount, lessening strain on the hands and elbows of the camera operator. The ergonomic grip design allows for a comfortable feel during operation, helping to reduce fatigue and making it easy to move the camera about. The lens is sure to satisfy with its impressive combination of robust specifications, enhanced optical performance, and usability.

Built-in 2x Extender Increases the Maximum Zoom Range to 200mm
The built-in 2x extender expands the lens to an impressive 200mm on the telephoto end, while maintaining 4K UHD optical performance throughout the entire range.

Compatibility with Existing Canon Focus and Zoom Demands and Accessories
The CJ20ex5B IASE T allows for full-servo zoom and focus control and is compatible with Canon's broadcast focus and zoom demands. It allows for the use of zoom and focus control accessories (such as the ZDJ-G01 and FDJ-G01).

- Angled 20-Pin Connector - Allows the camera to be placed on a flat surface with a 20-pin cable connected.

- New USB-C Port - Allows Drive Unit settings to be saved and loaded into other lenses. End users would be able to update firmware and can record and save maintenance history.

- New Information Display - Conveniently located on the top of the drive unit with a simplified menu.

- Focus Breathing Compensation - A feature which minimizes image distortion when racking focus. This setting can easily be turned on or off depending on preference.
- Ergonomic Design - Designed to reduce arm fatigue.
- Improved Servo Control - Faster iris speed.

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.

Virtual Output

12-pin Serial Communication
The CJ20’s serial connection with a remote control-compatible camera transmits focus, zoom, and iris position information and allows remote control of the camera.
Supports ARIA1 Camera Feature
ARIA (Automatic Restoration of Illumination Attenuation) adjusts illumination so that light is more evenly distributed between the wide and the telephoto ends of the lens. First, the Camera-lens communication at initialization identifies the lens attached. When zooming, the camera’s gain is increased starting at the F-drop/ramping point. Simultaneously, Peripheral Illumination Correction corrects light fall-off from the center of the frame to the periphery, This correction more evenly distributes light throughout the entire image.

ARIA OFF - Wide End

ARIA OFF - When zoomed in, the whole image is darker, especially the edges

ARIA ON - Correction makes light more even throughout image
