ABSTRACT:
This invention relates to a single-lens mirror reflex camera for studio purposes, with which the exposure-determining film exposure, within a prescribed opening time of the shutter, is effected during the duration of a flashlight initiated by the camera. A shutter cap is provided which is formed as a swivellable, light-tight return swinging mirror. Such cap is fixed on a driveable shaft, and is held by means of a return spring in the rest position completing the optical system of the viewfinder. The cap also carries at least one contact element of a control switch for the flashlight, of which the coacting contact is arranged on a stop limiting the open position.
