1. A camera, comprising:

  • a plurality of integrally formed electrostatic actuators, each actuator configured to exert a force on at least one lens, wherein each actuator comprises a fixed portion, a movable portion configured to move, relative to the fixed portion, between a first position, in which the actuator is operable, and a second position, in which the actuator is non-operable, and a latch configured to latch the movable portion in the first position;

    an optical image stabilization (OIS) algorithm module configured to command the plurality of actuators to actuate the at least one lens responsive to motion of the camera; and

    a driver integrated circuit operable to drive the actuators responsive to the OIS algorithm module'"'"'s commands.
