| Joux Sténo-Jumelle Plate Camera image by Steve Given (Image rights) |
The Sténo-Jumelle is a plate camera made by Lucien Joux & Compagnie of Paris from about 1895. It was made in two sizes, for twelve 9x12cm plates, or eighteen 6.5x9cm plates.[1]
As other cameras of the jumelle type, the body of the camera tapers toward the front. Its construction is unusual because it has an innovative plate-changing method. The body 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, so the whole thing has something of the appearance of a fire-bellows. 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 (the camera must be held with the lens uppermost for this operation, as it relies on the weight of the plate[2]). The camera and its plate-changing mechanism are the subject of a patent by Lucien Joux.[3][4]
The camera appears to have been substantially redesigned in around 1898. Collection Appareils reproduces an extract from l'Annuaire de la Photographie of 1898,[2] in which the Sténo-Jumelle is described as of all-metal construction, and so more compact. Earlier cameras, including some of the examples linked below, have part-wooden bodies.
Examples of the camera have various lenses, mostly by Krauss, including an f/8 Krauss-Zeiss Anastigmat[5][6][7] and an f/4.5 Tessar, also made by Krauss under licence,[8] (the Tessar itself was only patented in 1902, so this must be a late example of the camera). One example has a lens by Chevalier.[9] The 1898 information at Collection Appareils lists lenses for the metal-bodied camera as f/8 Zeiss Series IIa anastigmats (110mm and 136mm for the 6.5x9cm and 9x12cm cameras respectively; these are presumably the Krauss-Zeiss lenses seen on the examples linked here), or Goerz Series III anastigmats (110mm f/7.7 for the smaller camera, 130mm f/7.1 for the larger); no examples with these Goerz lenses have been seen.
The 1898 information at Collection Appareils refers to helical focusing on the lens (down to 1.5 metre for the 6.5x9cm camera, and 2 metre for the 9x12cm one). This is visible in some of the examples seen;[9][10] The others have a large lever on the left of the body, behind the shutter unit, which may be for focusing.
The shutter is a guillotine type, behind the lens: Frans Jacobs in his blog The Camera Collector stated that it is a five-speed shutter.[10] The speed selector and I/B/T selector are on the lens board. There is a Newton-type finder on the top, with an aiming pointer in front of the glass.
