ABSTRACT:
A photographic finder camera adapted to use interchangeable photographic lens objectives and having a photoelectric detector system for measuring the light flux passing through the photographic lens objective employed in each case. At least one movably mounted optical component is disposed in the camera housing which component directs at least a part of the light flux coming from the object to be measured and passing through the lens objective to the photoelectric detector system. Control means are provided to selectively move this optical component into the measurement position in the beam path of the camera lens objective and depending on the actuation of the shutter, to transfer the optical component into a non-use position.
