Abstract
An optical apparatus includes a lens movably supported, a driving part arranged to rotate for causing the lens to move, a moving mechanism arranged to cause the lens to move by the rotation of the driving part, and an adjusting mechanism arranged to cause the moving mechanism to move the lens for fine adjustment by applying rotational driving to the moving mechanism without recourse to the driving part.
