PURPOSE:To perform the display for both a focus detecting position and the manual switching state of a focus control mode, by setting a reflector which turns round an axis orthogonal to an optical axis on the front optical axis of a photographing lens having an automatic focusing mechanism. CONSTITUTION:A both-sided reflector 5 is set centering on a photographing lens 7 having an automatic focusing mechanism so that it can freely turn round a shaft 5a. The image of a mark 16 showing the focus detecting position within a viewfield is irradiated by a lamp 15 and relected to the left side on the rear surface of the reflector 5 to be displayed double within the photographing viewfield of a viewfinder by a half mirror 3. When the reflector 4 is tilted, the field optical axis of the lens 7 varies to vary the angle viewing the photographing field of a photodetector 13. At the same time, the position of the mark 16 also moves within the viewfield. The reflector 5 is turned so as to be parallel to a reflector frame 6 when the switching is carried out to the manual focus control. Thus a viewfinder of double image matching type is obtained to realize the manual confirmation. |
