An imaging apparatus comprising: a photographic operating device including two-step operational positions having at least a half-pressed position and a full-pressed position; a ranging device for measuring a distance to a subject; a fill-light radiating device for radiating fill light to the subject; a focus-adjustment controlling device for controlling adjustment of a focus based on a measured result of the ranging device; an exposure controlling device for controlling an exposure; a fill-light determining device for determining whether the fill light is required; and when the photographic operating device is pressed to the half-pressed position, the ranging device measures a distance to the subject without irradiating the fill-light (10-3, 11-3); after the ranging device measures the distance while the photographic operating device is in the half-pressed position a determination of whether a re-ranging is required is made (10-4, 11-4); characterized in that if re-ranging is required and the fill-light determining device determines that the fill light is required, the focus-adjustment controlling device does not adjust the focussing until the photographic operating device is in the full-pressed position, whereupon the fill-light radiating device radiates the fill light to the subject and the re-ranging is achieved by-the ranging device (10-14, 11-15), the focus-adjustment controlling device computes a focus adjusting position based on a result of the re-ranging, and the exposure is achieved by the exposure controlling device after the focus adjustment is controlled by the focus-adjustment controlling device based on the focus adjusting position. a photographic operating device including two-step operational positions having at least a half-pressed position and a full-pressed position; a ranging device for measuring a distance to a subject; a fill-light radiating device for radiating fill light to the subject; a focus-adjustment controlling device for controlling adjustment of a focus based on a measured result of the ranging device; an exposure controlling device for controlling an exposure; a fill-light determining device for determining whether the fill light is required; and when the photographic operating device is pressed to the half-pressed position, the ranging device measures a distance to the subject without irradiating the fill-light (10-3, 11-3); after the ranging device measures the distance while the photographic operating device is in the half-pressed position a determination of whether a re-ranging is required is made (10-4, 11-4); characterized in that if re-ranging is required and the fill-light determining device determines that the fill light is required, the focus-adjustment controlling device does not adjust the focussing until the photographic operating device is in the full-pressed position, whereupon the fill-light radiating device radiates the fill light to the subject and the re-ranging is achieved by-the ranging device (10-14, 11-15), the focus-adjustment controlling device computes a focus adjusting position based on a result of the re-ranging, and the exposure is achieved by the exposure controlling device after the focus adjustment is controlled by the focus-adjustment controlling device based on the focus adjusting position.
