An image-taking apparatus is disclosed which can achieve an appropriate AF control regardless of a zoom magnification. The image-taking apparatus has an image pickup element which photoelectrically converts an image of an object formed by an image-taking optical system including a focusing lens, and a signal processing circuit which produces an image signal based on an output signal from the image pickup element and has an electronic zoom function of electrically processing a part of the image signal to produce an enlarged output image. The image-taking apparatus also has a detection unit which detects a defocus amount between two image of the object, and a focus control circuit which controls a drive of the focusing lens in a first control method based on the output signal from the image pickup element and a second control method based on an output signal from the detection unit.
