With the shift to high image quality video contents using 4K cameras for television productions, lenses with high optical performance for cinema cameras have been receiving a lot of attention. However, as the shooting method differs between cinema and television camera lenses, there are difficulties in operation of cinema camera lenses for television production.

As a new idea for cine lenses, Fujifilm introduced the ZK series lenses, with detachable servo drive unit for zooming and focusing. In August 2012, the Fujinon ZK4.7x19 was released, followed by the telephoto type Fujinon ZK3.5x85 in November of the same year.

Thanks to the detachable servo drive unit on the ZK series, the lenses can be operated in the same manner as a traditional portable television camera lens. They are suitable for television productions with cinema cameras or use in traditional film production. The ZK series features high quality images due to the pleasing Bokeh and the shallow depth-of-field that is specific to cine lenses.

With the servo drive unit removed traditional manual adjustment or external cine motors for zoom and focus can be used.

With the release of the ZK2.5x14, the ZK series line-up consists of wide angle, standard, and telephoto lenses. The ZK2.5x14 is a wide angle zoom lens with a focal length covering from 14 to 35mm, supporting both film and digital cinema cameras. With the latest optical simulation technology and high precision large diameter aspherical elements, Fujinon have achieved both high optical performance and a lightweight compact body of just 2.9kg. Thanks to high resolution from the center to corner, high image quality without image distortion will be exhibited on the large screens of movie theaters. Additionally, a Macro Function is also standard, allowing for the shooting of subjects as close as 33cm, expanding the range of the lens.

High optical quality and lightweight, compact design

With the latest optical simulation technology and high precision large diameter aspherical lens elements, it has achieved both high optical performance and a lightweight compact body of 2.9kg. High resolution image without image distortion will be exhibited on the large screens of movie theaters. As with television lenses, a back focus adjustment mechanism is standard. This adjustment allows the lens to be optimized with the camera, to bring out the best in optical performance.Thanks to the 9-brade round iris, it will exhibit natural round circle Bokeh.

A wide angle lens covering focal lengths from 14mm to 35mm

Coupled with the ZK4.7x19 and ZK3.5x85, the ZK series supports a wide variety of scenes. Macro Function enables shooting subjects as close as 33cm. expanding the range of the lens.

Detachable servo drive unit

Thanks to the detachable servo drive unit on the ZK series, the lens can be operated in the same manner as a traditional portable television camera lens and accessories. The pleasing Bokeh and the shallow depth-of-field specific to cinema camera lenses can also be used for shooting commercials and dramas.

Installation of Rotary Encoder for high resolution output of lens data.

16bit Rotary Encoders are installed on the drive unit for high resolution output of lens position data, including zoom, focus, and iris.

Universal design

It features universal design for distance, focal length and T-No. scales. The original font is easy to read and luminous, on the focus, zoom, and iris (aperture) operation ring. It is comfortable to operate in all shooting situations.
