The Steno-Jumelle is a plate camera made by Lucien Joux & Compagnie of Paris from about 1895. It was made in two sizes, for twelve 9×12 cm plates, or eighteen 6.5×9 cm plates.[1]

As other cameras of the 'jumelle' type, the body of the camera tapers toward the front. It is constructed as two half-boxes, one inside the other (or a box and its lid). The two are hinged together at the front, and the upper part can be lifted up at the back. The upper part contains a plate magazine, and lifting and lowering it serves to move the most recently exposed plate from the front of the magazine to the back. This mechanism is the subject of a patent by Lucien Joux.[2][3]

Examples of the camera have various lenses, including an f/8 Krauss-Zeiss Anastigmat.[4][5][6][7][8] The shutter is a guillotine type. Most examples have a large lever on the left (which appears to be the speed control) and an I/B/T selector on the lens board. There is a Newton-type finder on the top, with an aiming pointer in front of the glass.
