An ophthalmologic apparatus obtains a suitable defocus state early in split AF even immediately after the apparatus shifts to an fundus observation state. At the time of focus state detection immediately after the shift to the fundus observation state, the apparatus tarns the fundus observing illumination light off if a focus determination unit determines that the defocus amount is equal to or more than a predetermined value, and turns the fundus observing illumination light on if the focus determination unit determines that an in-focus state immediately before photographing is obtained, thereby allowing the examiner to check a fundus state immediately before photographing.
