Camera apparatus

摘要

A camera system having a lens unit provided with an actuator for changing the state of an optical system by driving a driving part and a driving circuit which drives the actuator on the basis of a driving control instruction signal supplied in a given periodicity from a control circuit disposed on the side of a camera body. The lens unit is characterized in that the actuator driving timing of the driving circuit is arranged to differ from the timing at which the driving control instruction signal is supplied from the control circuit to the driving circuit.
