Ever since the first colour television content aired in 1962, Fujifilm has pursued the
development of broadcast-quality lenses for the television industry; and with the
shift to 4K broadcasting on the horizon it remains committed to delivering high-
precision optical technology.
Fujifilm’s HK-Series of cine zoom lenses with 8K-class optical performance was
introduced in 2009. In 2012 the 4K-class ZK-Series was launched, which were
lighter in weight and incorporated detachable full servo 16-bit drive units. Both the
HK and ZK lens series played a major role in the 4K test broadcasts of numerous
global sporting events including the Confederation Cup and World Cup.
The demand for 4K video content has increased year-on-year with shipments of 4K-
compatible television sets rising to approximately 11.6 million units last year and
the launch of a dedicated 4K channel in Japan in March 2015. The broadcasting
industry, which generally uses cameras (including 4K cameras) equipped with 2/3-
inch sensors, requires compatible broadcast lenses which can deliver advanced
ultra-high definition optical performance. Based on that requirement Fujifilm
recently developed and launched its UA-Series of 2/3′ 4K UHD TV lens models:
UA80x9 BESM and UA22x8 BERD. Honed by decades of development and enhanced
with cutting-edge optical technology, the high resolution, high contrast and high
dynamic range of Fujinon lenses delivers the 4K optical performance demanded by
imaging professionals.
Minimal aberrations over the entire zoom range are achieved by a newly developed
zoom group approach and floating focus system. True 4K imaging expression rich in
colour reproduction is achieved by an increased red and blue transmittance ratio
which is a benefit of the HT-EBC (Electron Beam) coating with the highest
transmittance and lowest reflectivity ratios achievable with current production
technologies.
Optical loss is significantly reduced to achieve 4K-class imaging expression rich in
colour gamut reproduction. The 4K image quality not only displays suppression of a
variety of aberrations, but also remarkable sharpness and clarity. The UA-Series
has integrated 16-bit encoders which can provide high-resolution lens data output
including extremely accurate zoom, iris and focus data. This capability and interface
promise enhanced compatibility with virtual systems for composing CG with live
broadcast images.
Fujifilm continues its commitment to develop optical, high precision forming and
assembling technologies and supply innovative products which address the
diversifying needs of broadcasting production. Fujifilm has been engaged in the
development and production of Fujinon TV and Cine lenses for over 50 years,
enabling exceptional image creation around the globe.
