A lens apparatus includes: a movable optical member; a driving unit that drives the movable optical member; an operating unit that operates the driving unit; a first controller that derives an input value for operating the driving unit based on an operation amount of the operating unit; a second controller that corrects the input value input from the first controller to calculate a control value and outputs the control value to the driving unit; and a deriving unit that derives a matching position from the control value. When an operation from the operating unit becomes effective, the deriving unit outputs the matching position to the first controller, and the first controller sets the matching position to the input value.
