The famous press cameras of Graflex were made in a number of variants and in several formats. The earliest models were available in 3x4, 4x5 and 5x7 formats. By 1939-1940 the 5x7 format was dropped and the 2¼x 3¼ format was added. Focal plane shutters were available from the beginning until 1970. Models with a focal plane shutter can use lenses mounted in shutters or barrel lenses (without shutters). The Pacemaker Crown Graphic, introduced in 1947, was the first model available without a focal plane shutter.
