The fixed slit shutter of Graflex is shown here in a view from the back of the camera, and fully disassembled camera below. The belows mechanism, and interchangeable lenses gave this camera the versatility that victor Hasselblad grew up with, and later took it one step further in his own camera. The mirror in this camera is sequential: The shutter is released after the mirror reaches its up position. It takes 1/8 of a second for the mirror go up!
