PURPOSE: To satisfy the required high operability of a television camera easily, by providing a servocontrol circuit section for speed control and a servocontrol circuit section for position control within the same servocontrol module and making these servocontrol circuit sections selectable by signals from the outside.

CONSTITUTION: A servocontrol module 3 which servodrives a zoom lens and a servocontrol module 4 which servodrives a focusing lens are mounted in a zoom lens body 1 mounted in a television camera body 2. These servocontrol modules 3 and 4 are constituted mutually commonly or by having interchangeability. The servodriving control signals to these modules 3 and 4 are formed by the potentiometers contained in a focusing knob 5 and a zooming knob 6 mounted to an operating rod, etc. and are introduced through cables. The servodriving feedback signals to the modules 3 and 4 are formed and introduced by potentiometers.
