An image capture apparatus comprises an image sensor including at least three focus detecting pixels, an optical axis displacement unit which displaces an optical axis of an imaging optical system by driving at least part of the imaging optical system, and a focus adjustment unit which performs focus adjustment by a phase-difference detection method using a pair of images detected in the at least three focus detecting pixels, wherein if the optical axis displacement unit moves the at least part of the imaging optical system, the focus adjustment unit performs focus adjustment using detection results of a pair of focus detecting pixels, among the at least three focus detecting pixels, other than a focus detecting pixel in which a common part of an exit pupil area and the light-receiving area of the focus detecting pixel is smallest.
