Fujifilm announced the development of the 4K broadcast lens, the FUJINON UA107X8.4 AF (Advanced Focus), the world’s first box lens that features the Advanced Focus function*1. The UA107x8.4 AF is due to be released in the spring of 2020.
The UA107x8.4 AF broadcast lens incorporates a newly developed phase-detection autofocus sensor, achieving fast, tack sharp images with a response speed as fast as 0.5 seconds and boasting an outstanding capability in tracking a moving subject. The lens also features the company’s proprietary image stabilization mechanism and a 107x ultra-magnification zoom that covers focal lengths from 8.4mm to 900mm (1800mm with 2x).
Among the features that make this lens a perfect choice for covering live sports and entertainment are High Dynamic Range (HDR) and vivid color reproduction. In addition to using aspherical and fluorite elements** to effectively control various types of aberration, the company’s unique multi-layer coating (High Transmittance Electron Beam Coating) boosts the rate of light transmittance, making it possible to deliver vivid color reproduction, as well as HDR-based rich tonal gradation, even under bright sun or at dusk.
The UA107x8.4 AF is a revolutionary product that will transform the way video is produced, as it allows for shooting high image quality 4K video with ease.
UA107x8.4 AF
The penetration of 4K-compatible large-screen television in recent years has increased opportunities for enjoying ultra-high-definition 4K video. As such, advanced skills are required from camera operators to manually achieve fast, precise focusing. To meet the needs of today’s videographers, Fujifilm has developed a 4K-compatible broadcast lens equipped with the AF function.
The UA107x8.4 AF’s phase-detection AF sensor and dedicated algorithm was developed with the technological expertise fostered from Fujifilm’s X Series and GFX digital cameras.
Fujifilm will debut the FUJINON UA107x8.4 AF at the Beijing International Radio, TV & Film Exhibition (BIRTV2019), to be held from August 21 to August 24, 2019.
