A lens barrel has a first lens group, a second lens group, a third lens group, a first support frame for supporting the first lens group, a second support frame for supporting the second lens group, a third support frame for supporting the third lens group, a first drive unit, and a second drive unit. The first lens group has an overall negative refractive power, and includes a prism. The second support frame is driven along a second optical axis by the first drive unit. The third support frame is driven along the second optical axis by the second drive unit. Part of a first movement region in which the second support frame moves overlaps a second movement region in which the third support frame moves.
