Abstract

PURPOSE: To display the operating direction of a distance-adjusting ring and achieve the improvement of operating characteristic by making the marks consisting light emitting display devices in arc form.
CONSTITUTION: The marks 21', 23' consisting of light emitting display devices are formed in arc form with respect to the center of the visual field frame 20 in the finder and similar marks 21", 23" are formed in arc form with respect to the center C2 of a distance adjusting ring 3. The marks 21', 21" show the rear focus state, the marks 23', 23" the front and rear focus state and the marks 23', 23" the front focus state. By such arc-form display, the photographer is readily able to discriminate the focusing operation state for the focused points 22', 22".
