FUJIFILM Experience the
Next Phase in Lens Design
FUJIFILM Japan has advanced its Experience the
Next Phase in Lens Design...

F

UJIFILM debuted the Fujinon
UA125X8BESM
(UA125X8),
a
4K-compatible broadcast lens hailed as
the highest 125x zoom ratio lens, and
the Fujinon UA107x8.4 AF (Advanced
Focus) 4K broadcast lens, the world's
first 4K box lens that features the
Advanced Focus function.
Fujinon
also
announced
the
availability of its ARIA (Automatic
Restoration
of
Illumination
Attenuation) and RBF (Remote Back
Focus) features. Two additional
Fujinon 8K broadcast lenses are under
development.
UA125X8
Fujinon's UA125X8 improved
optical
image
stabilisation
technology was one of the
highlights showcased during a
virtual press conference.
The UA125X8 box lens
covers a focal length from the wideangle of 8mm to 1000mm, with an
F1.7 aperture. It is now the longest
and widest 4K field lens for Ultra
HD applications in the Fujinon UA
series, designed for unparalleled 4K
performance imaging from today's
new 4K 2/3" cameras. The new lens
uses the company's proprietary
optical technologies to achieve vivid
colour reproduction and high contrast,
producing video with rich gradation
using HDR, which makes it a perfect
choice for live coverage of sporting
and music events.
In addition to having the highest
125X zoom magnification, the UA125X8
also boasts advanced 4K-compatible
optical performance, image-resolving
capability and rich gradation of
tones. It also has high-performance
optical image stabilisation, nine-blade

aperture for natural bokeh, and
is equipped with 16-bit encoders.
The UA125x8 employs the latest
High Transmittance Electron Beam
Coating (HT-EBC) resulting in richer
colours and greatly improved blue
response and transmittance. HT-EBC,
coupled with Fujifilm's exclusive
Aspheric
Technology,
reduces
ghost and flare, and increases light
transmission. A proprietary antifogging design minimises lens fogging
and reduces downtime due to moisture
- a critical concern when shooting in all
types of weather conditions.

Fujinon UA107x8.4 AF (Advanced Focus)

The penetration of 4K-compatible
large-screen television in recent
years has increased opportunities
for enjoying high-definition 4K video.
Amidst accelerated introduction of
4K-compatible video equipment, there
is a growing need at the production
frontline for high-magnification
zoom lenses capable of capturing
dynamic close-up video of a distant
subject in 4K quality. Thanks to the
world's highest 125X magnification
zoom and optical performance
that supports 4K video, the UA125X
can capture facial expressions and
gestures of athletes on the field and
performers on stage. Having the
world's highest wide-angle focal
length means the lens can also capture
an entire sporting or live music venue.
Advanced Focus UA107x8.4
An
updated
Fujinon
UA107x8.4 AF (Advanced
Focus) 4K broadcast lens, the
world's first 4K box lens that
features the Advanced Focus
function, was also debuted.
The UA107x8.4 AF incorporates a
