A collapsible-type lens barrel includes an image blurring correction unit
that drives a first lens in a plane orthogonal to an optical axis so as
to cancel shaking of an image sensing apparatus, and a second lens placed
adjacent the image blurring correction unit. When the collapsible-type
lens barrel is in the collapsed state, the image blurring correction unit
causes the first lens to withdraw to a position away from the optical
axis of the second lens, and causes the second lens to retract in such a
manner that a portion of the second lens enters at least part of a space
on the optical axis produced by the withdrawal of the first lens.
