ABSTRACT:
A single lens mirror reflex camera arranged for very fast operation. Both the reflex mirror and the auxiliary shutter or protecting flap are moved very quickly from viewing position to picture-taking position, without jar or vibration, by means of separate operating linkages which are in an angular position while the mirror and flap are in viewing position, and which straighten out to straight-line or dead-center positions as the mirror and flap move to picture-taking position, thus bringing them to a smooth stop. A step-by-step electrical switch controls various functions of the camera at various step positions of the switch. One step initiates the running of an electric motor which serves both to wind the film in the camera and to restore the mirror and auxiliary shutter from picture-taking position to viewing position.
