You can switch focus spool diret to optics, or via a servo motor via the six pin HRS (HIROSE) connector.
Do you use them new digital Canon lenses, so you need to use a
cable adapter, we use as the analog input on the optics.
Zoom mounted on the side of gimbol handle.
Send one photos so you can see how I have mounted on my Ultra 2
Sorry for my bad English, but I think that you get a good picture of how it works.
