Graflex Speed Graphic Camera 

Kodak Ektar 127mm f/4.7 Lens in Graphic Supermatic X shutter

The Speed Graphic was a press camera produced by Graflex in Rochester, New York. Although the first Speed Graphic cameras were produced in 1912, production of later versions continued until 1973 with the most significant improvements occurring in 1947 with the introduction of the Pacemaker Speed Graphic and Pacemaker Crown Graphic.

The "Speed" name derives from the maximum speed of 1/1000 sec. that could be achieved with the focal plane shutter. The Speed Graphic was available in 2¼ x 3¼ inch, 3¼ x 4¼ inch, 5 x 7 inch and the most common format 4 x 5 inch. Because of the focal plane shutter, the Speed Graphic can also use lenses that do not have shutters. 

The Speed Graphic was a slow camera. Each exposure required the photographer to change the film holder, open the lens shutter, cock the focal plane shutter, remove the dark slide from the inserted film holder, focus the camera, and release the focal plane shutter.
