PURPOSE:To let focusing display appear in the mark position of the subject in the finder by providing a means of showing the focus display in the distance measurement indicating range in the finder frame of the camera. CONSTITUTION:Light passes through a lens 1, then through the translucent portion 3 of a movable reflecting mirror 2 and arrives at a film face 4. On the other hand, the light reflected by the lower translucent auxiliary reflecting mirror 5 of the reflecting mirror 2 is detected by a focus detecting element 6 and the result thereof is operated and is displayed on a display element 8 (e.g., LED). The display of this LED is led to the translucent reflecting mirror 15 provided in a condenser lens 11 through a lens 13, where it is aligned with the light from the reflecting mirror 2 and is shown in the finder frame 7 through a pentagonal prism 16. The focusing position display is accomplished by showing the engraving of the mark 10 of the same shape as the configuration of the element 6 of + form on a focusing screen 9 in the finder frame 7 and displaying the focusing position with the focus detecting element 8 in the same position as the mark 10. |
