The Fujinon ZK25-300mm T3.5 to T3.85 Cabrio Lens is a 12x zoom for Super35 single-sensor cameras, features a PL mount and supports 4K production. The long zoom range allows you to shoot medium-wide to long shots without changing lenses, and it holds its maximum T3.5 aperture from 25 to 273mm, almost the entire length of the zoom, losing less than half a stop as it reaches 300mm. This minimized iris ramping makes it easier to use a continuous zoom along the entire zoom range of the lens.

The focus ring features 280 degrees of rotation, providing for accurate focus adjustments, and the 120-degree zoom rotation is consistent with other lenses in the Cabrio line. The focus, zoom, and iris barrels are geared with standard 0.8 film pitch, which provides an interface for the optional removable ENG-style digital drive unit. The rear PL mount features electrical contacts for sharing Arri LDS and Cooke /i Technology lens data with the camera.

An optional detachable drive unit converts the lens to an ENG configuration, and it incorporates a zoom rocker switch, 16-bit encoding, and an interface for remote control via a wired or wireless controller from Fujinon or other compatible, third party manufacturers. When the optional drive unit is attached to the lens, a digital auto-aligning system quickly and accurately calibrates it to the zoom, focus, and iris gears. Power is provided by either an external connector or the PL mount's "hot shoe" interface. Included with the lens is a 111mm clear protection filter that helps to protect the front of the lens.
