 Although they have less flexibility than monorail cameras, modern field cameras tend to have most camera movements for the front standard, i.e.lens rise/fall/shift/tilt/swing, but are usually more limited in back movements, sometimes having only tilt/swing.They usually use sheet film, in sizes from 6x9cm (2.4×3.6") to 20×24 inches (e.g., the Polaroid 20×24 camera), but the most popular "standard" sizes are 4×5 and 8×10 inches.
