4K UHD Field Box Lenses
Canon Store: $
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.
* Among compatible 2/3-inch 4K broadcast lenses available as of September 8th, 2015.

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.
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.
