Fujinon UA70x8.7BESM-T35 (w/o Trunk) 4K Premier Box Lens - 16608488

The UA70x8.7 offers 70x zoom, covering the focal lengths from 8.7mm in wide angle and 610mm in telephoto.

The floating focus system, which controls multiple lens groups according to the shooting distance, achieves high-resolution footage across the entire zoom range. It produces dynamic 4K video in various scenes, such as concert coverage or live broadcast, zooming from a wide view of the venue straight into an artist on stage.

FEATURES
70x zoom lens covering the most frequently-used focal lengths from 8.7mm in wide angle to 610mm in telephoto
Cutting-edge optical design to produce dynamic 4K footage in a diverse range of scenes
Natural bokeh achieved with a nine-blade diaphragm
Stock-standard 16-bit encoder

4K Ultra HD 2/3” Lenses for Broadcast -UA Series-

Introducing the New Expanded 4K Broadcast Lens Lineup from FUJINON

[image] Concept of Fujinon 4K lenses which have high resolution, high dynamic range, high contrast, and chromatic aberration reduction

4K demands a higher dimension of performance, and the expanded FUJINON 4K broadcast lens lineup meets the challenge.
Extending the limits of “High Resolution”, “High Contrast”, “Chromatic Aberration Reduction” and “High Dynamic Range”, FUJINON’s cutting-edge optical technology presents the next standard in optical performance – image quality that exceeds the high expectations of imaging professionals.

High Resolution
Resolution that matches the ultra-fine pitch of 4K pixels results in crisp and crystal clear images.

High Contrast
Superb image sharpness is achieved by improving MTF even for low-frequency objects that are generally common in the image.

Chromatic Aberration Reduction
The combination of fluorite ED (extra low dispersion)  and super ED lens elements minimizes color fringing and delivers clear, crisp images.

High Dynamic Range
To take full advantage of the expanded dynamic range offered by HDR cameras, we rigorously suppress flare and faithfully transmit the important “blacks” in video image rendering.

Key technology

1. Multi-group zoom system
[image] Zoom group highlighted example

By employing a multi-group zoom structure, aberrations are suppressed over the entire zoom range from wide angle to telephoto, realizing high image quality.

2. Large-aperture aspherical lens

Using a high-precision large-aperture aspherical lens element ensures high MTF to the very edges of the image.

3. Improved surface accuracy

Development of new polishing techniques and improvements in measurement precision achieve surface accuracy more than three times higher than that of HD, contributing to higher image quality.

4. New coating system
[image] Reflection versus almost no reflection in barrel

Adopting HT-EBC coating technology that achieves a low 0.2% reflection or less over a wide spectrum of wavelengths keeps surface reflection of the lens to the absolute minimum and makes it possible to render truer “blacks”.
 In addition, camera adjustment is easier because the transmittance balance is improved from the shortest to the longest visible wavelengths.

5. Development of new barrel design

Optimizing the shape of the lens barrel interior as well as its surface treatment effectively suppresses ghosting and flares.

Natural bokeh achieved with nine iris blades

By adopting nine iris blades, FUJINON 4K lenses achieve a nearly circular aperture. This makes it possible to render images taking full advantage of a softer, more natural bokeh.
