Abstract
An optical apparatus includes first and second lens groups, a guide barrel having a straight-guiding groove, a cam barrel, and an interlocking member having a first coupling portion. The cam barrel includes a first cam groove that moves the first lens group and a second cam groove that is different from the first cam groove and moves the interlocking member. When the second lens group changes a focal length range of an optical system from a second focal length range to a first focal length range, the first lens group is moved in a direction of an optical axis by the straight-guiding groove and the first cam groove, the interlocking member is moved in the direction of the optical axis by the straight-guiding groove and the second cam groove, and the first coupling portion withdraws the second lens group to outside of an optical path of the first lens group.
