UHD DIGISUPER 90

World's Highest Zoom Ratio and Longest Focal Length

As a broadcast lens that supports 2/3" 4K cameras, the 4K UHD DIGISUPER 90 (UJ90x9B) broadcast lens features the world's highest zoom ratio (90x)* and world's longest focal length (810mm)*. The lens is capable of maintaining full 4K overall optical image quality over that the full 9mm to 810mm 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.

4K Optical Performance

The 4K UHD DIGISUPER 90 (UJ90x9B) broadcast lens achieves a high Modulation Transfer Function (MTF) at picture center throughout the entire focal range of the lens, over a wide range of scene subject distances. This was a design priority. New design strategies were used to sustain a high MTF from picture center across the entire image plane to help ensure high subjective 4K image sharpness. New design strategies and new optical materials were utilized to lower the monochromatic and the chromatic optical aberrations to a level consistent with high quality 4K portrayal on large screens.

4K Optical Performance even with the Built-In 2x Extender and Image Stabilizer

Thanks to the precision of its high-grade components and assembly, the 4K UHD DIGISUPER 90 (UJ90x9B) broadcast lens achieves outstanding 4K optical performance, even when the built-in 2x extender has been engaged. The perennial challenge for long telephoto lenses is image blur caused by inadvertent movements of the lens often caused by to vibrations due to wind, or 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 ensure 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.

Applicability and Ease of Operation Ideal for 4K Shooting

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 90 (UJ90x9B) 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.

Compatible with HD Lens Systems

The 4K UHD DIGISUPER 90 (UJ90x9B) 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.
