HistoryEdit

The Graflex is a single-lens reflex camera, first produced in 1898 in New York, N.Y by the Folmer & Schwing Manufacturing Company of New York, NY. In the early years it was made in a variety of formats, settling down in the 1920s to a number of long-lived models which share the same basic design and mode of operation. Most models were for sheet film, some were made for usage with rollfilm.

The Graflex vertical focal-plane shutter consists of a single curtain with a series of four slits of widths from 1½ inches to 1/8; inch. The shutter spring can be set to six different tensions. Different combinations of slit width and spring tension allow a choice of 24 speeds ranging from 1/10 to 1/1000 as well as Time. When the shutter is released, the mirror swings up and triggers the curtain to travel from top to bottom. In the last models the tension settings were reduced to a simple High and Low, permitting 8 different speeds.

The standard lenses are for the most part f/4.5 Kodak Anastigmats and, in later years, Kodak Ektars. The rare Series C, a 3¼×4¼ model, is equipped with an immense f/2.5 Taylor-Hobson-Cooke lens.

All Graflex models feature the distinctive tall focusing hood that folds under the lid of the camera.

In 1927 Kodak divested itself of the Folmer-Schwing division, which re-organized as the Folmer-Graflex corporation. Folmer-Graflex, which also manufactured the Graphic press cameras, was finally dissolved in 1973. The last of the Graflex SLRs was produced in 1963.

ModelsEdit

Most Graflex cameras were made with a revolving (actually rotating) back, abbreviated to RB, which allowed shooting in vertical or horizontal orientations without turning the camera. All were made of straight-grain Honduras mahogany covered with black Morocco leather. The Graflex back is unique: the various film holders and magazines that fit the Graphic cameras will not fit the Graflex cameras and vice-versa.
