    Hi,
    is it possible to control broadcast lenses with built focus and zoom servo motors without using external servo for example canon HJ11ex4.7b IASE by cable connected to movi pro?

    It is possible to "control" FIZ via LANC using the MOVI Pro Controller, but that assumes that your camera is connected to the lens and knows how to drive it. The main problem is that you cannot use the big iris and focus wheels or the zoom rocker, but need to use the small settings knobs to send LANC "impulses", which makes smooth changes almost impossible. I do not know about the Pilot or Mimic, but I assume it is the same there.)

    If you are using the Movi Pro handheld, it is probably simplest to just run another cable along the gimbal axes and use a good old fashioned LANC controller and circumvent the Movi Pro completly for lens control.

    If you are mounting the Movi Pro somewhere and also insist on using the Freefly ecosystem for FIZ, it is best to disassemble the motor drive of your B4 lens and get external motors. Chrosziel CDM-100s are solid and not as expensive as some of the other options. Keep an eye out for the correct modulus wheels for the motor as B4 lenses tend to use smaller teeth than the standard cinema mod 0.8.
