Abstract: A detecting member for detecting that an exposure control member is in operation keeps the main switch of an exposure indicating circuit closed to energize the indicating circuit while the amount of exposure is being controlled. Upon completion of exposure control, the detecting member opens the switch to deenergize the indicating circuit independently of the action of the shutter.

Abstract: A device which actuates a flash circuit in a camera whenever the brightness of the scene being photographed is too low for the taking of pictures by ambient illumination. A switch is arranged on the member which arrests the needle pointer of a conventional galvanometer in an exposure meter circuit.

Abstract: A finder parallax correction lens capable of giving a visual indication, a supplementary lens and a glass protector for the main taking lens are aligned in a planar arrangement and movably built in the camera. When the supplementary lens for photographing subjects at near or close distances is placed in front of the main taking lens with its optical axis in alignment with that of the taking lens, the correction lens is set in position for the finder optical system, visually indicating that it is so positioned, with the glass protector brought to its retracted position. A lock mechanism is further provided which permits the shutter to be tripped only when the lenses and glass protector are set in correct photographing positions respectively and which otherwise locks the shutter against tripping.
