Fujifilm launches a new portable zoom lens “FUJINON UA46×9.5BERD”

• Realizes a 46x zoom, the world’s highest^*1 magnification in a broadcast portable lens for 4K video production
• Supports a wide variety of video productions with High Dynamic Range and a wide angle of 9.5mm, the world’s widest angle^*2 lens in its class with vivid color reproduction and high contrast
• Provides a stable and accurate shooting environment due to our newly developed, high-performance anti-vibration mechanism and drive unit

FUJIFILM Corporation (President: Kenji Sukeno) will launch the “FUJINON UA46x9.5BERD” (UA46×9.5) lens featuring the world’s highest^*1 zoom ratio in a portable lens for 4K video production at 46x. The lens is scheduled for release in January 2019.

The UA46x9.5 covers a focal length from 9.5mm to a high magnification of 437mm, making it the world’s widest angle^*2 lens in its class. It is a portable broadcast zoom lens that enables incredible video to be shot in a wide variety of scenes. Using state-of-the-art optical design technology, it suppresses color aberrations to the minimum. Also, it realizes vivid color reproduction and high contrast by improving the light transmittance. Rich tones are reproduced with High Dynamic Range (HDR). Furthermore, it provides a stable and accurate shooting environment due to a newly developed high-performance anti-vibration mechanism and drive unit. This provides a great image in support of creating 4K sports broadcasts, nature documentaries, news coverage and other 4K video applications. In addition, it supports a variety of production requirements when combined with an HD broadcast camera.

Fujifilm will be exhibiting the “UA46x9.5” at the Beijing International Radio, TV & Film Exhibition (BIRTV2018), to be held from August 22 to 25

The introduction of 4K-compatible broadcasting equipment is currently accelerating in sports broadcasts such as soccer and baseball, and the amount of 4K video content is expanding worldwide. Also in Japan, the need for 4K video production is increasing as “New 4K/8K Satellite Broadcasting“ starts from December 2018. Additionally, demand for shooting high quality HDR images, which vividly reflects high contrast, for conventional HD productions is increasing. Reflecting such growing needs from users, high performance broadcast lenses are increasingly in demand. The new “UA46x9.5” features the world’s highest magnification* zoom ratio in a 4K broadcast portable lens, achieving a 46x zoom. It covers a focal length from 9.5mm to a high magnification of 437mm, making it the world’s widest angle** lens in its class. It supports a wide range of situations, from shooting with the entire background to close-ups of subjects. It also utilizes state-of-the-art optical design technology to suppress various aberrations to a minimum. Furthermore, by improving the light transmittance with Fujifilm’s proprietary multi-layer coating, it realizes vivid color reproduction and high contrast. It is possible to capture images taking advantage of HDR and rich tones are reproduced even for scenes shot at dusk or in strong sunlight when there is a great amount of contrast. Since it features a newly developed anti-vibration mechanism and drive unit, it can also be used to shoot video with little shaking and accurate operation. The “UA46x9.5” strongly supports not only sports broadcasts, but also nature documentaries, news coverage, and the production of other 4K video.

Since it can also be mounted on HD broadcast cameras, higher quality HDR video can be taken while effectively utilizing existing broadcast equipment

Fujifilm is planning to expand the lineup of our broadcast portable lenses for 4K video production, with the introduction of the “FUJINON UA46x13.5BERD” scheduled to be released next spring. It features the same 46x zoom ratio as the “UA46x9.5” and covers a focal length from 13.5mm to 621mm

FUJINON lenses by Fujifilm are known for high quality eloquent images and have been used in various production applications including movies, TV commercials, and live sports broadcasts around the world. Fujifilm will continue to tap into its optical, high precision forming and assembling technologies that have been nurtured over many years in the field of video expression, to further expand and enhance its 4K lens lineup, thereby addressing the diversifying needs of production requirements.

1. Product name, release date and price

2. Main features

(1) The world’s highest zoom ratio in a broadcast portable lens for 4K video production, realizing a 46x zoom

• By adopting a “multi-group zoom method,” which moves multiple lens groups to zoom, as well as precision formed large aperture aspherical lenses, a 46x zoom ratio has been achieved, the world’s highest* zoom ratio in a portable lens for 4K broadcasting. Out-of-focus blurring during zooming, which often occurs with high magnification zoom lenses, can be suppressed to the minimum for clear shooting across the entire zoom range
• Ultra-high refraction lenses suppress distortion to the greatest extent possible that is likely to occur when shooting at the wide angle focal length. It covers a focal length from 9.5mm to a high magnification 437mm, making it the world’s widest angle^*2 lens in its class and allowing it to support various requirements, from shooting with (in English this does not have a meaning) to close-ups of subjects.
• Realizes incredible 4K video for sports broadcasts, nature documentaries, news coverage, and more.

(2) Reproduces rich tones using state-of-the-art optical design technology

• Axial and magnification chromatic aberrations^*4 are suppressed to the minimum thanks to state-of-the-art optical design technology using ED and fluorite lenses^*3. Additionally, Fujifilm's proprietary “HT-EBC (High Transmittance Electron Beam Coating)” multi-layer coating is applied for a high level of transmittance and realizes vivid color reproduction and high contrast. This makes it possible to shoot with HDR, reproducing rich tones even for scenes shot at dusk or strong sunlight when there is a great amount of contrast.
• Since it can also be mounted on HD broadcast cameras, higher quality HDR video can be shot while effectively utilizing existing broadcast equipment

^{*3 Lenses using fluorite and featuring a small chromatic dispersion for the refractive index and light transmittance. Realizes an optical design with an extremely small level of chromatic aberration.}

^{*4 Aberrations caused by differences in refractive indices depending on the light wavelength. Axial chromatic aberrations occur when focal points do not match and the image blurs. Magnification chromatic aberrations occur when colors blur on the sides of the image.}

(3) Equipped with a proprietary anti-vibration mechanism, supporting 4K video production

• A High-performance gyro sensor allows minute vibrations to be accurately detected.
• Features an anti-vibration mechanism based on the proprietary “ceramic ball roller system.” Using precision formed ceramic balls for the drive section reduces frictional resistance while preventing vibration to the greatest extent possible and accurately corrects image blurring caused by wind or vibrations without time lag.
• Suppresses stuttering^*5 when moving the camera horizontally, which can easily occur when panning. This allows framing to be performed as intended.

^{*5 A phenomenon in which panning is detected as sway and unintentional correction is applied, causing the framing to return slightly.}

(4) Newly developed drive unit realizes a high level of operability

• The newly developed drive unit improves the drive speed of the zoom, focus, and iris, realizing an accurate level of operability. This makes smooth zooming possible and allows moving subjects to be quickly and accurately grasped
• The lens comes with 16-bit encoders*6, capable of making high-resolution output of lens data including zoom and focal position information. It can be linked with various other systems such as a virtual studio system for combining CG images with live action footage

^{*6 A sensor for converting position information into digital signals. Zoom and focus position data is divided in 16-bit resolution and output as electric signals.}

(5) Realizes natural bokeh with the adoption of a nine aperture blade design

• An aperture shape closer to that of a circle is realized by adopting nine aperture blades, allowing for images making use of beautiful beams of light and a more natural bokeh.
