Optical apparatus, optical element driving unit, and photographing system

摘要

An optical apparatus has an operation member for permitting a first operation and a second operation; a position detector for detecting a position of an optical element; a target position setting device for permitting arbitrary setting of a target position in driving of the optical element; and a control for controlling the driving of the optical element. The control stores the position of the optical element detected by the position detector and drives the optical element to the target position set by the target position setting device, in response to the first operation of the operation member, and the control drives the optical element to the stored position of the optical element detected by the position detector, in response to the second operation of the operation member.
