FUJIFILM Announces New FUJINON HZK25-1000mm Broadcast Zoom Lens

FUJIFILM has announced the development of the FUJINON HZK25-1000mm (HZK25-1000mm) broadcast zoom lens, which boasts the world’s highest1 40x zoom and the world’s longest focal length1 of 1000mm.

The HZK25-1000mm is a box-type broadcast zoom lens in the dual format, supporting two types of large image sensors. It can be mounted on cameras equipped with the Super 35mm sensor or the even larger sensor equivalent to 35mm full frame*2. The lens achieves optical performance which exceeds 4K. It also facilitates the use of cinema cameras which is becoming increasingly common in the broadcast industry, offering cinematic visual expressions such as shallow depth-of-field for beautiful bokeh in live coverage of sporting events and music concerts. The HZK25-1000mm is due to be released in the spring of 2023.

Today, in the broadcast industry, cinema cameras equipped with a sensor larger than the industry’s mainstream sensor*3 are increasingly used in live coverage of sporting events and music concerts, amidst the growing needs for immersive cinematic expressions involving the use of bokeh and high dynamic range. However, cinema camera lenses are optimised for shooting movies and TV commercials, and therefore have a smaller zoom magnification ratio than that of broadcast lenses. They also require a specialist in focus operations, which is uncommon in the broadcast industry. For these reasons, there has been a demand for a high-magnification zoom that supports a large sensor and can be operated in the same way as box-type broadcast lenses.

The new HZK25-1000mm is a broadcast zoom lens that uses optical technology, nurtured over many years, to deliver the world’s highest 40x zoom and the world’s longest focal length of 1000mm. It is designed in the dual format, supporting two types of large sensors. The lens normally works with the Super 35mm sensor, and also supports a sensor equivalent to 35mm full frame by way of activating the built-in expander*4 to expand the image circle by 1.5 times. It offers the added benefit of maintaining the same angle of view in both sensors.

The lens also provides F2.8 aperture, enabling cinematographic visual expressions with shallow depth-of-field and resulting beautiful bokeh. The use of large-diameter aspherical lens and fluorite lens*5 controls various forms of aberration thoroughly to achieve optical performance which exceeds 4K. The lens maintains the operation of broadcast lenses involving zoom demand and focus demand even when mounted on a cinema camera. It can also be used with a variety of existing accessories*6.

  • *1 Among box-type broadcast zoom lenses compatible with a sensor larger than the Super 35mm, as of October 19, 2022 according to FUJIFILM data.
  • *2 Capable of covering an image circle measuring 28.5mm across the entire zoom range when combined with a camera equipped with a Super 35mm sensor and covering an image circle measuring 41.3mm across the entire zoom range when combined with a camera equipped with a sensor equivalent to 35mm full frame; Image circle refers to a circular area where lights that have passed through the lens form an image.
  • *3 2/3-inch sensor.
  • *4 The expander can expand the image circle and extend the focal length to the telephoto side.
  • *5 Lens element made of fluorite, which has a characteristically small wavelength dispersion in light refractive indices; It enables optical design with minimal chromatic aberration.
  • *6 Limited to accessories specifically designed for box-type FUJINON broadcast lenses.
