The Single Axis Unit SXU-1 is a simple single channel hand unit that can be set up to control focus, iris or zoom. The SXU-1 can be used along the WCU-4 for separate iris control, perhaps operated by the cinematographer in situations where subtle exposure adjustments are required during travelling shots. Alternatively it can be used with the SMC-1 single motor controller, providing a simple, low cost option to productions that do not need multi-axis wireless lens control.
