A lens barrel and a photographing apparatus including the lens barrel include a clutch assembly disposed on a plane orthogonal to an optical axis between a manual adjustment ring and a distance adjustment ring. The clutch assembly rotates on a fixing part of the lens barrel and includes first, second, and third clutch wheels and one or more rollers, wherein the first clutch wheel includes an operator disposed on an end thereof and that receives a rotation force of the manual adjustment ring, the second clutch wheel is disposed on an inner surface of the first clutch wheel, the third clutch wheel is disposed on an inner surface of the second clutch wheel and fixed to the distance adjustment ring, and the rollers are radially disposed with respect to the optical axis and comprise surfaces contacting the operator and other surfaces contacting an outer surface of the third clutch wheel, wherein the first and second clutch wheels are elastically fixed to each other by first elastic members, a second elastic member is disposed between the second clutch wheel and the fixing part, and a third elastic member is disposed at both ends of the second clutch wheel, supports ends of circumferential surfaces of the rollers, and controls positions of the rollers.
