Control apparatus, optical apparatus, control method, and storage medium

A control apparatus configured to control movements of a first optical element and a second optical element in an optical axis direction, the control apparatus comprising:

• one or more memories storing instructions;
• and
• one or more processors that, upon execution of the instructions, operate to:
• acquire information on a reference position of the first optical element at each of a plurality of first reference positions, at least one of the plurality of first reference positions being located within a movable range of the second optical element, and
• set, in a specific control for moving the first optical element for detecting the reference position and moving the second optical element to a predetermined position within the movable range, a specific reference position among the plurality of first reference positions, the specific reference position being used for the detecting, to a first reference position located outside a movement path of the second optical element to the predetermined position.
