Abstract
The present invention provides a lens barrel in which all lens groups are attached to a leading cylindrical body. A movable lens group of the lens groups is moved by a driving source incorporated in the leading cylindrical body. The lens barrel is less likely to be influenced by external forces and can be made smaller. The lens barrel includes first, second, and third cylinders, and first, second, and third lens groups attached to the third cylinder, which is extended first among the first, second, and third cylinders. The first and third lens groups are fixed to the third cylinder, and the second lens group is disposed between the first and third lens groups and movable along the optical axis.
