CONSTITUTION: In the case of macro photographing, by operating a knob 16, a lens holder is rotated and a sector 65 abuts on a stopper 58, then a macro lens is positioned and fixed on the photographing optical axis 13. A target mark 19 exists at a position which departs from the center of the visual field of a finder 18 and the center of a viewing angle at the time of macro photographing is displayed. Since armatures 48 and 49 are connected because of the contact of metallic plates 71 and 72 even though a stroboscope pressing part is not pressed, in such a case, a main capacitor is charged and photographing with strobe light is performed just by depressing a shutter button. Thus, the under-exposure caused by making the aperture of a diaphragm small is effectively prevented.
