An imaging apparatus includes an autofocus function, and performs focus adjustment by displacing a focus lens to an in-focus opposition. A focal correction calculation unit calculates a focal correction amount using at least one type of information selected from the diaphragm information used for exposure adjustment, positional information for the zoom lens, and positional information for the focus lens. The focal correction amount is further revised, and processing is executed to suppress coloring on the subject image resulting from chromatic aberration. The correction amount after revision is sent to a focal adjustment unit and the focal lens is driven and controlled by the lens control unit.
