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.
