Claim:
1. A lens barrel comprising: a lens; a rotatable operation member; a rotation amount detector configured to detect a rotation amount of the operation member; an operation detector configured to detect a rotational operation of the operation member, the operation detector having a mechanism that is different from a mechanism of the rotation amount detector; and a controller configured to perform drive control of the lens depending on rotation of the operation member, wherein the controller is configured to operate the lens barrel in a first mode in which the rotation amount detector is used to detect the rotation amount of the operation member and is configured to operate the lens barrel in a second mode in which the operation detector is used to detect the rotational operation of the operation member, and power consumption required in the second mode is less than power consumption required in the first mode.
