A lens driving system (100) configured to be mounted on a lens device (10) has: a variable power lens driving section (120) moves a variable power lens group (26) in an optical axis direction (P); a focus lens driving section (130) moves a focal lens group (36) in the optical axis direction (P); a receiving section (140) that receives an operation signal (R_CTR) for remotely operating the variable power lens driving section (120) and the focus lens driving section (130); a control section (160) that generates a control signal for controlling the variable power lens driving section and the focus lens driving section based on the operation signal, and a power section (150) that is charged with at least a part of the operation power supplied to a drive section from a camera device (70) and supplies the charged power to the variable power lens driving section, the focus lens driving section, the receiving section, and the control section as operation power.
