4K UHD Field Box Lenses

Item Code: 5774C002AA


First 4K AF Lens to achieve 122x Optical Zoom (1000mm) with Widest Angle* (8.2mm)

The UHD-DIGISUPER 122AF is the first 4K AF lens with 1000mm on the telephoto end* (2000mm with the built-in 2x extender), making it ideal for shooting live sports, nature, concerts, live events, and other applications where focal length is prioritized. Combined with a best-in-class 8.2mm wide setting*, the UHD-DIGISUPER 122AF broadcast lens is ideal for a wide range of in 4K UHD broadcast television productions.

The lens can maintain full 4K overall optical image quality over the full 8.2mm to 1000mm range, offering superb image framing options for all forms of outside broadcast television productions. The extensive framing latitude can dramatically capture all possible on-site sensations - from the emotion of an entire crowded stadium to other emotions expressed in the close-ups of facial expressions of individual players on the field.

AF Function Enables Automatic and Simple Focusing

Focusing can be quite difficult in certain telephoto shots with shallow depth, requiring camera operators to have advanced skills. The UHD-DIGISUPER 122AF features an Auto Focus function that focuses automatically and simply, enabling easy and smooth high-quality 4K video even when used by operators without specialized skills. It also provides dependable servo performance (Approx. 0.6 sec. high speed zoom) from wide angle to telephoto so that users can supply excellent quality video for sports broadcasts, stadium giant concerts and live broadcasts.

Exterior-mounted Information Display

An exterior-mounted Information Display enables an operator to easily make a variety of function and settings adjustments. The display can show the lens status when doing an internal check, allows changing of settings for each lens function according to shooting equipment and conditions, and can show support information for troubleshooting and finding solutions.

Outstanding Optical Performance for 4K Cameras

The UHD-DIGISUPER 122AF broadcast lens was built using our exclusive optical design technology, helping ensure consistent 4K resolving power and high contrast from the center of the screen to the periphery, maintaining 4K optical performance even when the 2x extender is deployed.

Zoom fluctuation is controlled using a multi-group movable zoom and aspheric surfaces. This facilitates consistent and dependable optical performance from the center of the image to the edges. In addition, integrated floating focus system helps reduce changes in aberrations when focusing to different object distances, while maintaining 4K optical performance in color reproduction over the entire focus range, especially on the telephoto side.

The lens also features a combination of the latest materials, contemporary optical design, and multi-layer coatings to produce outstanding 4K imagery. This helps lower the monochromatic and chromatic optical aberrations to a level consistent with the highest quality 4K portrayal on large screens, allowing 4K cameras to reach their potential and deliver performance in live sports such as baseball, soccer and golf.

Minimized Chromatic Aberration

Fluorite and UD glass have also been generously utilized and optimally arranged for better correction of chromatic aberrations. This helps increase image clarity with less color bleeding or coloring around the outlines, achieving superb color reproduction to the edges of the images.

Reduced Ghosting and Flare

Special coatings and an internal lens barrel designed to prevent reflection result in minimized ghosting and flaring, allowing users to take high-tonality images to support HDR. The UHD-DIGISUPER 122AF is the first broadcast AF lens to feature Canon's Air Sphere Coating (ASC), which combines vapor-deposited multi-layer coatings with an ultra-low refractive index outermost layer. The lens coatings help to control the reflection on the lens barrel’s inner surface, helping suppress ghosting and flaring, resulting in HDR-compatible high-contrast imagery.

BT.2020 Support

The lens also features correction data that supports BT.2020, enabling excellent color reproduction to the corners of the screen when attached to a 4K camera.

Ideal for HDR Image Capture

HDR images offer excellent gradation representation and enhanced realism and dimension including texture for image representation close to the real thing. However, there can be noticeable color bleeding and flare, so HDR shooting requires high optical performance. Canon's exclusive optical design technology and Air Sphere Coating (ASC) allows the UHD-DIGISUPER 122AF to deliver the advanced optical performance essential for an HDR system lens, enabling the capture of more realistic imagery.

Dependable Image Stabilization Performance in 4K

Shooting in 4K is demanding - even the slightest vibration can greatly impact image quality. The UHD-DIGISUPER 122AF employs Canon's optical and servo technologies to help ensure 4K performance from wide angle to telephoto even when using Image Stabilization (IS).

The UHD-DIGISUPER 122AF broadcast lens can achieve high vibration reduction rates in higher frequency bands (with excellent performance at the telephoto end) and stable operation even when panning.

Constant Angle Focus System (CAFS) Minimizes Focus Breathing

This function brings changes in angle of view due to focusing ("breathing") down to near zero. It functions by counteracting the zoom effect by the focus group movement to cancel out the effect on the angle of view.

Bokeh Effect

With the optional MCJ-S02 Macro Controller, the focus position of the UHD-DIGISUPER 122AF can be changed as the focal length is adjusted when shooting in macro. This built-in feature can be utilized to support special techniques in which the focus position can be shifted within the same shot just by using the Macro Controller, allowing for subtle creative defocus effects. This can help provide a degree of creativity when shooting live events such as a concert.

Support for Virtual Systems

The UHD-DIGISUPER 122AF broadcast lens utilizes the same standard controllers for zoom and focus operations that have been optimized by Canon over decades. The lens also uses the standard Canon 20-pin connector that provides an interface for the digital precision positional information of the zoom, focus, and iris operations required by many external virtual systems. The positional data is internally created by high precision digital encoders.

Compatible with Existing Lens Controllers


The UHD-DIGISUPER 122AF broadcast lens offers compatibility with HD demands used for broadcasting. Operators can continue using the zoom/focus motorized accessories and servo models they currently use with HD equipment, as well as Canon's ZDJ-S01 Zoom Demand, FDJ-S01 Focus Demand, and the FDJ-S41 Focus Demand. These zoom and focus demands are equipped with the flexibility necessary to meet the new and diverse user needs when shooting in 4K, while offering simple operability in a compact design.
