An image-taking apparatus capable of appropriate AF control without depending on a zoom enlargement ratio is disclosed. The image-taking apparatus includes a signal processing section which generates an image signal based on the output signal of an image-pickup device and has an electronic zoom function electrically processing part of the image signal to generate an enlarged output image and a controller which controls the driving of the focus lens by using a first control method and a second control method which is different from the first control method. The controller changes a control method to be used between the first and second control method in a first zooming state including at least a state in which the electronic zoom function is not in use and a second zooming state using the electronic zoom function which has a zoom enlargement ratio larger than that of the first zooming state.
