An image-taking apparatus is disclosed which enables the accuracy of re-performance determination of in-focus search control to reliably maintain an in-focus state in response to a condition change after focusing is achieved. The image-taking apparatus comprise a first detector which outputs a focus evaluation value signal and a second detector which outputs a detection signal different from the focus evaluation value signal. The image-taking apparatus comprises a controller which performs a first control for controlling drive of the focus lens such that an in-focus position of the focus lens is searched for on the basis of the focus evaluation value signal. The controller obtains shift information which represents a shift state from an in-focus state based on the detection signal from the second detector after the first control, and performs processing associated with the re-performance of the first control based on at least the shift information.
