If you want to power a Canon Cine Servo, typically you would use a D-Tap to Hirose connector. There are many vendors that supply these cables including Texas Media Systems. And this will work fine if you have a rig or battery that has an extra D-Tap DC power output terminal. Unfortunately, the Sony F5 does not have a D-Tap DC power output terminal block anywhere on the camera. Also, because the back of the F5 is designed to accommodate Sony’s AXS-R5 RAW recorder, replacing the V-mount with an aftermarket plate that provides a D-TAP DC output terminal is not an option. The F5 does, however, have two Hirose 4 pin output terminals that can and will supply enough power to operate your Canon 17-120 Cine Servo.
The Hirose connectors will cost around $100. The procedure should only take a few hours if you’re skilled in fabricating cables. Or you can buy a premade cable from Texas Media Systems for $250.
