This side handle attaches to the M4 mounting holes on the Tiltaing camera cages for the Sony a7/a9 series and Canon 5D.
A battery port on the bottom of the handle allows you to use a Sony F570 battery to power the Nucleus Nano motor via the 8V Micro-USB power output. A 12V DC output is also integrated into the handle.
The handle also has a built-in R/S button to allow you to record run/stop your camera with a compatible R/S cable.
