an image-pickup element which photoelectrically converts an object image formed by an image-taking optical system which includes a focus lens;

a first detector which outputs a focus evaluation value signal which represents a focusing state of the image-taking optical system based on a predetermined frequency component of an output signal from the image-pickup element;

a second detector which outputs information about a distance to an object with triangulation; and

a controller which performs a first control for moving the focus lens to a position at which the focus evaluation value signal is at a relatively large level,

wherein the controller obtains shift information which represents a shift state from an in-focus state based on the information about the distance to the object with triangulation from the second detector after the first control, and performs processing associated with re-performance of the first control based on at least the shift information.
