ABSTRACT:
An optical apparatus is disclosed with which the correspondence between the movement of a movable lens and the position of an operating member can be maintained and the operability can be improved. The optical apparatus comprises a lens drive unit which drives a movable lens, an operating member operable within a predetermined movable range, and an operating member drive unit which drives the operating member within the predetermined movable range. The optical apparatus also comprises an operating member position detector detecting the position of the operating member, and a signal output unit that outputs a signal for moving the movable lens. The controller controls the drive of the lens drive unit based on a signal from the operating member position detector and controls the drive of the operating member drive unit based on the signal from the signal output unit.
