The Dr. Staeble Unoplast camera is a plate camera with triple extension bellows manufactured by Dr. Franz Staeble (München, Germany). It was offered in the following formats: 6 x 9; 9 x 12; 10 x 15; 13 x 18; and 18 x 24cm.[1] At least three versions are documented.
pre-World War I version
The pre World War I version seems to have been made of solid wood, with a centrally located Newton finder. The front board also has a fold-up wire frame sportsfinder.[2]
Another wooden 10x15 version exists with a Brilliant finder centrally mounted on the front board.[3]
post-World War I version
The well-built, very sturdy full-metal camera measures 192 X 186 X 90 mm (closed), 244 mm (opened). The maximum extended length is 363mm. Given the full metal body, the cameras weighs over 2kg.—The removable front board is set in a front standard with geared vertical movement (rise) but no sideways movement. The standard allows for tilt to 20º from the vertical, but only backwards. The lack of forward tilt of the standard is compensated by the folding bed which allows for two angles, the standard 90º, as well as 110º.—The camera body has a fold-up Newton finder placed at the top left and a water-filled spirit level mounted on the top right. There are two tripod sockets, a protruding reinforced socket on the folding bed and sunk one on the left hand side. A leather carry strap is on the right. While the camera has an almost square body with square bellows, but the camera back is a standard 10 x 15, mounted on a turnable plate so that it can be aligned vertically or horizontally. The actual negative size appears to be 95 x 145mm.[4]
In its standard version, the Unoplast camera came fitted with a Dr. Staeble Doppel-Anastigmat. Most units were delivered with a special quarter-turn bayonet that allowed for rapid exchange of the front cell while the back cell remained in place. Additional front cells, to achieve a variety of focal lengths, was sold as the Polyplast expansion set.
