ABSTRACT:
An optical apparatus having a first lens barrel member, a second lens barrel member having a larger diameter than a diameter of said first lens barrel member, an optical unit held by the second lens barrel member, and an image shake prevention optical device for preventing the image shake. The image shake prevention optical device is fixedly held on at least one of the first and second lens barrel members between the optical unit and the first lens barrel member, and at least at a stepped portion formed by the first and second lens barrel members formed due to the difference between the diameters of the same. In this apparatus, a space formed along the second lens barrel member having a larger diameter can be efficiently utilized to arrange the image shake prevention optical device.
