OREANDA-NEWS. April 08, 2015. FUJIFILM Corporation (President: Shigehiro Nakajima) has announced the world's first launch, in July, of broadcast zoom lens that offers exceptional optical performance for use with 4K cameras. The latest release, “FUJINON UA80x9” (hereinafter “UA80x9”) is a 80x zoom lens that covers a broad range of focal lengths from 9mm in wide angle to 720mm in telephoto, making it ideal for the live coverage of sporting events and concerts.

The market needs for 4K video contents are surging amidst a 7-fold year-on-year increase in the shipment of 4K-compatible television sets to approx. 11.6 million units last year and the launch of a dedicated 4K channel (CS satellite broadcasting) in Japan in March this year. Fujifilm's lineup of cine lenses has included the “HK series”, which offers optical performance approximating to 8K systems, and “ZK series”, which combines 4K optical performance and electric drive units 4. With solid reputation not only from the film industry, but also from broadcasters producing 4K contents, lenses in both “HK” and “ZK” series are frequently used in test 4K broadcasts for international sporting events. However, the broadcasting industry generally uses cameras equipped with a 2/3-inch sensor including 4K cameras with the same sensor size, and is therefore seeking compatible broadcast lenses that deliver advanced optical performance.

“UA80x9”, is a broadcast zoom lens compatible with 4K cameras. Using the cutting-edge optical simulation technology, the lens achieves an impressive 80x zoom as well as advanced optical performance such as high image resolution, contrast and color reproduction. Covering the focal length from 9mm in wide angle to 720mm in telephoto, the lens features a unique “optical stabilization mechanism” that provides optimum adjustment to image shakes caused by vibrations and wind, making it an excellent choice in live coverage of sporting events and concerts. The “floating focus system”, which controls multiple lens groups according to the shooting distance, delivers high-resolution and high-contrast images from close-up to infinity, enabling 4K video production with a high realistic sensation and premium picture quality. With the demand for accurate focusing needed for 4K resolution, Fujinon's new focus position demand unit 5, the EPD-31A, has improved from 12 bit to 16bit encoding.

FUJINON lenses by Fujifilm are known for advanced descriptive performance, contributing to the evolution of video imaging through their use in the production of TV programs, movies and commercials across the world. Fujifilm will continue to tap into its optical, high precision forming and assembling technologies that have been nurtured over many years to develop and supply innovative products that address the diversifying needs of broadcasting production.
