ABSTRACT:
A rigid camera with a film holder independently rotatable about a horizontal axis and a vertical axis. The film holder rotates synchronously with the focusing plate of the viewfinder. The focusing plate rotates independently about a first horizontal axis parallel to the horizontal axis of the film holder when the film holder rotates about its horizontal axis, and about a second horizontal axis perpendicular to its first axis when the film plane rotates about its vertical axis.
