Optical apparatus

An optical apparatus comprising:

• a plurality of optical elements arranged in an optical axis direction;
• a first holding member and a second holding member configured to hold a first optical element and a second optical element, respectively, among the plurality of optical elements;
• a first guide member and a second guide member configured to guide movements of the first holding member and the second holding member, respectively, in the optical axis direction;
• a rotation stopping member configured to prevent rotation of the first holding member around the first guide member and stop rotation of the second holding member around the second guide member;
• a first driver and a second driver configured to drive the first holding member and the second holding member, respectively, in the optical axis direction;
• and
• a base member configured to hold the first driver and second driver,
• wherein when the optical apparatus is divided into three areas in a circumferential direction around an optical axis as a first area, a second area, and a third area when viewed from the optical axis direction, the first driver and the first guide member are disposed in the first area, the second driver and the second guide member are disposed in the second area, and the rotation stopping member is disposed in the third area, and
• wherein the first driver and second driver are disposed in two areas that at least partially overlap each other in the optical axis direction.
