Fujifilm has announced the FUJINON HZK25-1000mm F2.8-5.0. This box lens features a native PL mount, a zoom ratio of 40x, and a telephoto focal length of 1000mm, which makes it the highest combination of magnification and telephoto reach available to date for any lens that can be used on S35 and large format sensors.
   

The HZK25-1000 is a real feat of engineering. Not only does it feature a very large focal range, but the maximum aperture even when using the lens at 1000mm is just F5. As a comparison, the Canon CINE-SERVO 50-1000mm at 1000mm is T8.9. Yes, the Canon is a way smaller and lighter lens, but it is virtually unusable in low-light environments such as concerts, etc. when at the telephoto end.

The lens came about after FUJIFILM observed and gathered feedback from professionals working with digital cinema cameras in live production environments. FUJIFILM saw that there was a clear need for a PL mount lens that could cover a variety of larger sensors and offer a very large focal reach.

Digital cinema cameras with image sensors larger than existing B4-mount cameras have been increasingly popular for sports and live event broadcasting. The use of large-sensor cameras enables the expression of immersive images by offering smooth bokeh and high dynamic range for live broadcasting. While traditional lenses for single sensor cameras may be optimal for filming movies and commercials, the zoom ratio is considerably lower than that of a B4 mount lens, and lens characteristics when zooming and focusing are different from those applicable to lenses used in live broadcasting.

Dual-format system

HZK25-1000 deploys a dual-format system which means that it can support two single sensor sizes. This allows the lens to be used on both large format and super 35mm sensors. The HZK25-1000 enables shooting with the same field of view in both large format and super 35mm formats. Just to be crystal clear, you need to use the 1.5x extender for the lens to cover full frame sensors.

A 1.5x expander gives operators the ability to capture images at 1500mm. Additionally, when paired with a large format sensor, operators can shoot with a field of view equivalent to that of a super 35mm sensor while maintaining maximum optical performance.

The lens is 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.

Optical Image Stabilization

The lens is the first commercially available box-type zoom lens compatible with large sensors equipped with optical image stabilization. The latest anti-vibration mechanism and firmware utilize Fujifilm’s unique ceramic ball roller system. Not only does this mechanism provide a high level of anti-vibration performance against shaking caused by footholds and wind, but it also suppresses shaking of the hands to ensure stable image capture.

Other Features

Fujifilm’s proprietary optical technology is claimed to help suppress aberrations by using a large-aperture aspherical lens and a fluorite lens that has been polished. FUJIFILM states that by eliminating unnecessary ghosting, flare, and color fringe, the lens delivers high optical performance.

In addition to stabilization, HZK25-1000 features all of the latest technological advancements that are now standard in most of Fujifilm’s FUJINON broadcast lenses:

Automatic Restoration of Illumination Attenuation (ARIA)

Remote Back-Focus

Automatic Chromatic Aberration Correction

Pricing & Availability

The FUJINON HZK25-1,000mm F2.8-F5.0 is expected to be available in Spring 2023, however, there is currently no indication about pricing.
