ABSTRACT:
The camera includes a disengageable safety retaining catch for interchangeable lens objectives and an automatic focusing mechanism connected to a drive shaft for the transmission of rotary adjustment setting motions to the lens objective. The drive shaft operationally engages the automatic focusing mechanism via a drive and is provided with a spring supported in the axial direction. The rear end of the drive shaft is guided in a fixed bearing bushing. The front end is supported in a connection flange on the camera body. The front end is formed as a claw or toothed coupling element protruding beyond the connection flange and engages a complementary coupling piece which is disposed in a connection base on the lens objective.
