The Press Graflex was a 5×7" SLR. It got a special focal plane shutter which had speeds from 1/5 sec. up to 1/1500 sec. with narrow curtain slit or slower speeds with wider curtain slit. This was faster and less complicated than the focal plane shutters of the regular Graflex reflex cameras which were slower and had more slits. The camera could take lenses of focal lengthes between 7 and 14 inches.
