Provided is a drive control apparatus for a zoom lens apparatus which can maintain a focused condition for an object. The drive control apparatus for a zoom lens apparatus is composed of a first lens unit ( 103 ) adapted to displace for changing the power, and a second lens unit ( 105 ) located nearer to the image side than the first lens unit and adapted to displace for focus adjustment, comprising a control device ( 112 ) for controlling the drive of the first lens unit, and further controlling the drive of the second lens unit for maintaining a focused condition in association with the drive of the first lens unit. The control device limits the drive of the first lens unit in an zooming range in which a focused condition by the second lens unit can be maintained.
