Newly developed FUJINON HZK25-1000mm
Broadcast zoom lens that achieves the world’s highest 40x zoom and the world’s highest telephoto of 1000mm
Supports two large sensors, enabling cinema-like image expression that takes advantage of beautiful bokeh
FUJIFILM Corporation (Headquarters: Minato-ku, Tokyo; President and CEO: Teiichi Goto) is pleased to announce the release of the FUJINON HZK25-1000mm, a broadcast zoom lens that achieves the world’s highest ^*1 40x zoom and the world’s longest telephoto ^*1 of 1000mm. (hereinafter referred to as “HZK25-1000mm”).

The “HZK25-1000mm” is a box-type broadcast zoom lens with optical performance exceeding 4K and a dual format system compatible with two large sensors. ^*2 Can be used in combination with a camera equipped with a super 35mm sensor or a sensor equivalent to a 35mm full-frame sensor, which is larger than the Super 35mm sensor . In recent years, the use of cinema cameras in the broadcasting industry has been increasing, and cinema-like image expression that takes advantage of bokeh due to shallow depth of field can be achieved in sports broadcasts, live concerts, etc. The HZK25-1000mm is scheduled for release in the spring of 2023.

Our company plans to exhibit the “HZK25-1000mm” at the international broadcasting equipment exhibition “InterBEE 2022” to be held at Makuhari Messe (Chiba City, Chiba Prefecture) from November 16th to November 18th, 2022.

Currently, at shooting sites such as sports broadcasts and live concert broadcasts, there is a growing need for immersive image expression that takes advantage of bokeh and high dynamic range . Shooting with the installed cinema camera is progressing. However, since cinema camera lenses are optimized for shooting movies and commercials, they have limited zoom ratios compared to broadcast lenses, and they require dedicated focus operators. result in a different operation. Therefore, there is a demand for a high-magnification zoom lens that can be operated in the same way as a box-type broadcast lens while supporting large sensors.

The newly developed HZK25-1000mm is a broadcast zoom lens that utilizes optical technology cultivated over many years to achieve the world’s highest zoom of 40x and the world’s longest telephoto of 1000mm. “HZK25-1000mm” adopts a dual format method that supports two large sensors. It is normally compatible with Super 35mm sensors, but by using the built-in expander ^*4 to expand the image circle by 1.5 times, it is also compatible with sensors equivalent to full-frame 35mm. In addition, you can shoot with the same angle of view regardless of the sensor.

The HZK25-1000mm achieves a brightness of F2.8 at the wide-angle end, enabling cinema-like image expression that takes advantage of beautiful bokeh effects due to a shallow depth of field. The stone lens ^*5 thoroughly suppresses various types of aberration, demonstrating optical performance exceeding 4K. In addition, while attached to a cinema camera, it can be operated in the same style as a broadcast lens using zoom demand and focus demand. You can also use a wide range of accessories ^*6 that have already been released . In addition, it is equipped with an anti-vibration mechanism that employs a uniquely developed “ceramic ball roller system”. Accurately compensates for venue vibrations and wind sway for stable video recording.

Over the years, we have developed and provided broadcast lenses that meet the detailed needs of broadcast cameramen. We also have a lineup of 8K-compatible broadcasting lenses, and have been leading the way in improving image quality. In the cinema industry, starting with the launch of the HK Series in 2009, we have expanded our lineup of cinema camera lenses. Among the five series currently being developed, the Premista series, a cinema camera zoom lens compatible with large format sensors ^*7 , has received high praise from film production sites for movies and commercials for its overwhelming resolution and high convenience. increase. We will continue to develop and provide high-performance lenses and accessories that support comfortable shooting to meet the diversifying needs of video production sites.

*1 As a box-type broadcast zoom lens compatible with sensors larger than Super 35mm. As of October 19, 2022. Our research.

*2 When combined with a camera equipped with a super 35mm sensor, it covers an image circle of 28.5mm over the entire zoom range, and when combined with a camera equipped with a sensor equivalent to a full-frame 35mm, it covers an image circle of 41.3mm over the entire zoom range. possible. The image circle is the circular area where the light passing through the lens forms an image.

*3 2/3 inch sensor.

*4 It is possible to expand the image circle and extend the focal length to the telephoto side.

*5 A lens that uses fluorite, which has the advantage of small wavelength dispersion of the refractive index of light. An optical design with extremely small chromatic aberration can be achieved.

*6 Limited to exclusive accessories for box type FUJINON broadcast lenses.

*7 A larger image sensor than the Super 35mm sensor and 35mm full-size sensor, which are the mainstream formats for cinema cameras.

Record

1. Development product name
Broadcast zoom lens “FUJINON HZK25-1000mm”

2. Main features

(1) Achieved the world’s highest zoom ratio of 40x and the world’s highest telephoto distance of 1000mm
Broadcast lenses developed using optical technology cultivated over many years. It achieves the world’s best 40x zoom, covering focal lengths from 25mm wide-angle to 1000mm telephoto.

By using the expander built into the lens, it is possible to shift the focal length from 37.5 mm to 1500 mm, which is 1.5 times longer on the telephoto side. You can capture the subject at the intended size even from a distance.

(2) Compatible with Super 35mm sensor and sensor equivalent to 35mm full size
A dual format format compatible with two large sensors, which is the mainstream of cinema cameras, was adopted. Usually compatible with Super 35mm sensors. Furthermore, using the built-in expander expands the size of the image circle by 1.5 times, so it can also be used with cameras equipped with a sensor equivalent to a 35mm full-frame.

When combined with a camera equipped with a sensor equivalent to a 35mm full-frame sensor, it maximizes the superior optical performance while enabling shooting with the same angle of view as a super 35mm sensor.

(3) Cinema-like image expression that makes the most of beautiful bokeh effects
A large-diameter aspherical lens and fluorite lens that have been polished with high precision are used to thoroughly suppress various types of aberration. Demonstrates optical performance exceeding 4K. Furthermore, by suppressing ghosts, flares, and color bleeding, high-definition and natural rendering is achieved.

Despite being a high-magnification lens compatible with large sensors, it achieves a brightness of F2.8 on the wide-angle side. It is possible to shoot in low-light environments such as indoor concerts.

Bokeh effect simulation is performed using the proprietary optical design application “FOCUS”. We divided the out-of-focus area into several layers to verify the texture of the bokeh, and achieved a bokeh that naturally melts from the in-focus surface to the background. Cinema-like image expression that emphasizes the subject is possible.

(4) Equipped with the latest anti-vibration mechanism
Equipped with an anti-vibration mechanism that employs a proprietary “ceramic ball roller system”. In addition to exhibiting high anti-vibration performance against vibrations in the venue and swaying due to wind, it also suppresses swinging back to achieve stable video shooting.

(5) Can be operated using zoom demand and focus demand
While attached to a cinema camera, it can be operated in the same style as a broadcast lens using zoom demand and focus demand. You can also use accessories for box-type broadcast Fujinon lenses that are already on the market.

It also supports multi-camera operation that allows multiple cameras to shoot simultaneously. We support efficient video production.
