ABSTRACT:
A finder optical system suited to the electronic camera of the single lens reflex type, the camera having the movable mirror for making a finder optical axis (second optical axis) from the optical axis (first optical axis) of the photographic light beam, including at least one reflecting member for reflecting this second optical axis in a direction perpendicular to the first optical axis and the second optical axis bent by the movable mirror and a secondary image forming lens, whereby the height of the finder is lowered, and further, while improving the finder magnification, an erect non-reverse image can be observed, is disclosed. Disclosure is made also on the arrangement of the light measuring element and the automatic focus adjusting device suited to the electronic camera.
