A drive controller of a lens apparatus including a first lens unit movable to perform manual focus and a second lens unit disposed closer to an image than the first lens unit. The drive controller includes a detection device detecting a focal state of the lens apparatus, a storage device storing the detected focal state, and a control device controlling focus by driving the second lens unit to a focal position based on the detected focal state. The control device performs a compensation operation on the manual focus with the focus control after completion of the manual focus. The drive controller eliminates a clutch mechanism for selecting drive systems for the manual focus and focus adjustment and performs a focus adjustment (a compensation operation) after completion of the manual focus while minimizing a space needed for a rear focus unit to move.
