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

Introducing the New Expanded 4K Broadcast Lens Lineup from FUJINON

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

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. Development of new barrel design

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. New coating system

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.
