Chronology of cameras Graflex
Traduction de Daniel Fromm
The RB Auto Graflex is incontestably the most multipurpose of all the Graflex models.
One major modification was made in 1920, by lengthening the upper front part of the body and changing its form; this allowed use of longer lenses. The direction in which the viewing hood opens also changed in 1920.
The long bellows and broad range of focal lengths usable allows magnifications up to 1:1.
The front standard has rise/fall. The back is a rotating Graflex type (slotted film holder). The 4x5 was last offered in 1940, the 3x4 in 1942.
The 4x5 RB Auto Graflex is rare. Unmodified cameras are sought after.
