The Fujinon SS-01 is a full-servo (SS = servo/servo) rear lens control kit built for the Fujinon XA20sX lens, covering the complete range of servo zoom and focus functions from a single rear-mounted controller. The kit includes mounting clamps, a focus module and a combined zoom/focus demand, giving full remote control over both functions rather than a manual override on one side. It suits field recording and broadcast environments alike, including live event and sports coverage, where a rear operator needs consistent servo control of zoom and focus. The SS-01 is compatible with RM-type lenses and is built specifically for the 2/3" ENG XA20sX lens only.
