ARRI's SXU-1 Single Axis Unit is a wireless hand unit offering single-axis focus, iris, or zoom control. The compact SXU-1 features remote camera start/stop and tally, an ergonomic wooden handgrip, and a backlit, super-smooth control knob. This simple unit can be used in conjunction with the WCU-4 or with the SMC-1 single-motor controller (both available separately).
Addressing the fact that focus marks are only good if they're visible, the SXU-1's backlit display window is readable in bright sunlight, and its knob's internal light provides readability in low-light settings. One marking disk and a lanyard are included with the SXU-1 unit. A required battery and charger are not included and are available separately.
