Graflex also produced the Film Magazine. It is commonly referred to as a "bag magazine" (or "bag mag"), and uses a leather bag that hangs on the side of the frame to exchange the septums from front to back. It is a much more manual device than the Grafmatic, as exchanging a septum is done manually through the bag, rather than by a simple manipulation of the magazine's dark slide. They were sold in separate versions for film and glass plates, and held 12-18 sheets/plates, depending on the model. They are found in 3×4, 4×5, and 5×7 inch formats.
