PROBLEM TO BE SOLVED: To provide a focus information display system in which when focus information for a television lens system is displayed, information about the depth of a field is displayed so that a cameraman can recognize whether or not the distance of a subject in a focused position at which a focal point evaluation value is the peak is within the range of the depth of the field in relation to the distance of the subject in the present focused position, which prevents such inconvenience that the cameraman wastes time and effort to adjust focusing more accurately than is necessary. SOLUTION: A graph showing focused positions with reference to the horizontal axis and focal point evaluation values with reference to the vertical axis is displayed on the LCD 34 of a lens information display device 30 connected to a lens device. In addition, a band n showing the range of the depth of the field at the peak point T of the focal point evaluation value and an index P showing the present focused position are displayed.
