The 4K UHD-DIGISUPER 86 (UJ86x9.3B) broadcast lens offers a wide angle setting of 9.3mm that can be altered all the way to an impressive telephoto setting of 800mm, while maintaining full 4K overall optical image quality over that extended range. This 86x zoom range offers superb image framing options for all forms of outside broadcast television productions. This 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.
The highest attention was paid to making the highest Modulation Transfer Function (MTF) possible at picture center, and tightly maintaining this throughout the entire focal range of the 4K UHD-DIGISUPER 86 (UJ86x9.3B) broadcast lens, over a wide range of scene subject distances. New design strategies were used to sustain a high MTF from picture center across the entire image plane to help make the highest subjective 4K image sharpness possible. These new design strategies and optical materials were utilized to help lower the monochromatic and the chromatic optical aberrations to a level consistent with the highest quality 4K portrayal on large screens.
A particular challenge to the 4K UHD-DIGISUPER 86 (UJ86x9.3B) broadcast lens design is the built-in 2x optical extender. The insertion of that additional optical subsystem tends to exacerbate optical aberrations. Accordingly, Canon paid the utmost attention to the optical design of this unit and as a consequence full 4K optical specifications are protected when the extender is switched in.

A persistent challenge for long telephoto lenses is image blur caused by inadvertent movements of the lens, often caused by to vibrations due to wind, when mounted on towers. This becomes a larger issue when 4K image resolution is sought. The latest state of the art optical shift-type image stabilizer system (empowered by a powerful new digital servo control loop), helps facilitate high-speed precision deflection of light rays being transmitted through the lens, serving to counteract (in real time) their displacement by inadvertent outside movements of the lens.
Great consideration was given to the requisite precision mounting of all optical elements required to maintain full 4K performance over the extended focal range of the 4K UHD-DIGISUPER 86 (UJ86x9.3B) broadcast lens. Ensuring precision focus tracking over that long zoom rage was a central design priority. Digital servo speed has been optimized to meet the many operational requirements that support creative coverage of sporting events. Advanced, contemporary optomechanical design strategies were used to produce an overall lens size that contributes to its operational ease.
The 4K UHD-DIGISUPER 86 (UJ86x9.3B) broadcast lens utilizes the same standard controllers for zoom and focus operations that have been optimized over decades of Canon HDTV field lens developments. 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.

Augmented Creative Control: Innovations in Focus Demand and Zoom Demand Controllers for 4K UHD Long Zoom Field Lenses
Today, large format lens-camera systems have been adopted in many broadcast television productions and producers, directors, and camera operators have now become both attached to, and skilled in, the cinematic imagery and practices supported by these systems. In particular, the “rack focus” is much used in movie and episodic television dramas. This entails a subtle change in depth of field that reveals some new detail (can be an item or another human subject) in a scene – by careful manual operation of the lens focus control. Operational implementation involves changing the focus of the lens during a continuous shot – and this can be small or large changes of focus. If the focus is shallow, then the technique becomes more noticeable. It does demand precision control over focus accuracy.

Very wide rotation angles – typically 270 degrees or greater (from MOD to Infinity focus extremes) – has long been established in the cine lenses (both primes and zooms) used in the motion picture film world.
Role of the 2/3-inch Image Format in 4K UHD Production
This paper is intended to provide a background to the emergence of 2/3-inch lens-camera systems for 4K UHD production and the optical performance expectations of associated 4K lenses. The paper will review Canon’s involvement in the development of those lenses and will describe our initial 4K UHD lens family and the associated design strategies to achieve this impressive level of optical performance. The paper will explain the unprecedented strategy of introducing two categories within this new 4K UHD lens family – namely, 4K and 4K PREMIUM. The distinct performance difference between the two reflects Canon’s recognition that different 4K program genres will require different levels of overall cost / performance.
Lens Strategies for the era of 4K UHD Digital Motion Imaging
It was probably inevitable that broadcasters would begin to explore the possibilities of 4K UHD for the globally popular world of outside broadcast sports coverage; and indeed, recent years have seen a great deal of related experimental projects. The 4K UHD lens issue soon surfaced as the limitations of presently available Super 35mm zoom lenses quickly became apparent.
