Fujifilm has introduced two
new 8K broadcast zoom lenses, both capable of producing dynamic 8K
ultra-high-definition (UHD) images.
Fujifilm states that its Fujinon HP66X15.2ESM box
lens has the world’s longest 8K focal length of 1,000mm while also featuring
the world’s highest zoom magnification of 66x.
The company also unveiled the Fujinon HP12X7.6ERD, a
portable lens covering a range of 7.6mm to 91mm, offering the world’s widest 8K
angle of view at 93.3 degrees.
Both lenses were revealed during a virtual press
conference by Fujifilm this week following the cancellation of the NAB 2020 show
in Las Vegas, USA.
Both the HP66X15.2
and HP12X7.6 UHD lenses feature bayonet mounts targeting three 1.25”
sensors for ultra-high 8K resolution. This is bolstered by Fujifilm’s
multi-layer coating (High Transmittance Electron Beam Coating), which boosts
the rate of light transmittance, making it possible to deliver vivid color
reproduction, as well as high dynamic range (HDR)-based rich tonal gradation.
In addition to
using aspherical and fluorite elements to effectively control various types of
aberration, both lenses have a nine-blade
aperture for natural bokeh and are equipped with 16-bit encoders.
The HP66X15.2 also
features the latest high-performance optical image stabilisation mechanism to
make 8K production at long focal lengths rock steady.
“As
broadcast technology early adopters explore the challenges and benefits of 8K
production, there are growing needs for high-performance optical equipment
compatible with this technology,” said Yuji Igarashi, general manager,
Electronic Imaging Division & Optical Devices Division. “With four times
the resolution of 4K video, recording in 8K requires lenses with exceptionally
advanced optical performance.”
According to
Fujifilm, the use of UHD video is spreading globally, especially in live sports
coverage and documentary production; and it is expected to proliferate further,
with Japan having launched their 4K/8K UHD satellite broadcasts in December
2018, and China accelerating its move to adopt 8K broadcasts commercially this
year.
