A fundus camera capable of obtaining a fundus image while keeping a fixed field angle even if an eye is not emmetropia, and advantageously utilizing a photographed image for diagnosis. The camera includes a photographing optical system having a photographing optical axis, a focusing lens arranged movable along the axis in an optical-axis direction, and a first element which picks up a fundus image illuminated with illumination light for photographing via the lens, a unit which moves the lens, a unit which detects a position of the lens, a display, and a display control unit which synthesizes the fundus image picked up by the element within an opening of a display frame figure, a size of the opening determined by a detection result of the detecting unit, to display as an image keeping a fixed field angle regardless of visibility of the eye, and displays on the display.
