Abstract
A lens barrel comprises a first zoom/focus lens group and a second zoom/focus lens group configured to respectively vary a focal distance and imaging distance by moving in an optical axis, a first actuator configured to drive the first zoom/focus lens group, a second actuator configured to drive the second zoom/focus lens group, and a drive controller configured to independently control the first actuator and the second actuator. The drive controller is configured to wobble the first zoom/focus lens group by reciprocating only the first zoom/focus lens group out of the first and second zoom/focus lens groups in a optical axis direction.
