Preston Cinema Systems has been providing innovative camera and lens control systems for over 30 years. The Micro Force zoom control began this tradition by using force sensor technology to control zoom speed. In the years since its introduction, it has truly become the "industry standard" control.

Our FI+Z system has provided the motion picture industry with several breakthrough technologies. It was the first to employ 2.4 GHz spread spectrum technology for a wireless lens and camera control and was the first to provide digital motors for lens drives. These technologies have brought a uniquely high level of reliability and confidence to the film set such that the FI+Z is now considered a mainstream requirement on film sets worldwide.

In 2007, the Motion Picture Academy awarded a Scientific and Engineering Award for the development of the FI+Z system to Howard Preston and Mirko Kovacevic in recognition of its contribution to the motion picture industry

The newest member of the FI+Z family, the Hand Unit 3, is encased together with its microwave link in a splash-proof housing. "Lens Mapping" technology matches the focus markings of the lens to pre-printed fluorescent focus rings. Its features are described here.

New 3D functionality makes the FI+Z an essential tool for controlling both stereo lenses as well as 3D rigs. Lens Tweak software matches the stereo lenses while 3D rig software allows precise control of the IO and Convergence axes.
