The front focusing group of lens elements and the zooming group of lens elements are driven independently from one another to suppress focus shift while zooming, which eliminates the need to re-focus after zooming in or out. The optical and mechanical approach means there is no time lag as seen in an electrical control system.
The use of the front inner-focusing system controls lens breathing (change of angle of view during focusing which achieves smooth focusing in an impressive scene.
Manufacturing technology developed for conventional FUJINON cine lenses is applied to control optical axis shift while zooming, achieving intended composition every time.
