Abstract
A lens apparatus includes an optical system including a focus lens unit and a magnification-varying lens unit, and a processor configured to control driving of the focus lens unit. The processor is configured to acquire a detected position of the magnification-varying lens unit from a zoom position detector, and determine a target position of the focus lens unit according to a predicted position of the magnification-varying lens unit based on locus information indicating a relationship between a position of the magnification-varying lens unit and a position of the focus lens unit that is in focus at the position of the magnification-varying lens unit, and the detected position of the magnification-varying lens unit.
