The Zoom Control is designed for use with the CARTONI remote system.
The zoom controller will fit most tripod handles, rods, or other tubes.
It can be used to drive Servo lenses and remote motors.
It is possible to set the maximum desired speed on the dial, then use the pressure-sensitive rocker to vary the speed from a crawl all the way up to the preset max.
Alternatively, depress the rocker fully and roll the dial with your index finger to ramp the speed up.
Speed dial acts as a limiter for maximum speed or a “ramping” device.
