FUJIFILM North America Corporation is pleased to debut the updated FUJINON UA107x8.4 AF (Advanced Focus) 4K broadcast lens, the world’s first 4K box lens that features the Advanced Focus function*. The lens was showcased during a virtual press conference on April 16, 2020.
The UA107x8.4 AF incorporates a newly developed phase-detection auto focus sensor, achieving fast, tack sharp images with a response speed as fast as 0.45 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, entertainment, and House of Worship 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.
According to Dylan Kissel, a student at Michigan State University and sports camera operator for Spartan Vision, who tested the UA107X AF, “It was a really nice being able to just shoot whatever I wanted to and not have to worry about focus. I could whip up to somewhere in the crowd and get the shot, trusting that focus would be there and know I could get back to the game in time. By the end of the first time out, I was very comfortable with it all. I knew the lens was going to take care of me while I got the shots I needed. I didn’t have to worry about taking those extra few seconds to get the focus, and the director didn’t have to worry about it either because he knew it was going to be there and could take my shot.”
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.
“With the advent of 4K video, focus has become critically important in live production and Fujinon’s assisted focus solves the problem with an adaptive, extremely fast and accurate tool that works in even the most demanding lighting conditions,” said David Lemmink, Director of Engineering/Director of Operations, Solotech.
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.
