The Fujinon 4K UA14x4.5 BERD ENG-Style Lens with Servo Zoom and Doubler is a 4.5 to 63mm zoom lens, designed to support 4K origination and provide 2/3" cameras with an ultra-wide-to-telephoto angle of view. The lens has a 14x zoom ratio, and when you engage the built-in 2x extender you double the focal length range. The maximum aperture is a fast f/1.8 from 4.5 to 41mm and ramps to f/2.8 at 63mm. The HA14x4.5BERD features a digital servo for zoom control, and focus can be either manual- or servo-controlled.

Innerfocus minimizes the effects of lens breathing, which ensures a more consistent angle of view when making focus adjustments. QuickZoom improves zoom speed to 0.7 seconds end to end. With the push of a button, QuickZoom facilitates a rapid shift to the telephoto end to check focus. Releasing the button automatically returns the lens to the previously selected focal length.
