OTAG (Österreichisches Telefon AG) was a maker of telephones and radio sets in Vienna in the early 20th century. The company is known for only one camera, from about 1925 to 1930. It is a simple viewfinder camera for 35 mm cine film, invented by Jacques Singer. This was mostly sold as the Amourette, but Collection Appareils shows the same camera (or a very similar one) named the Lutin, and suggests this name was only used in France. This may have been simply a matter of good taste (an 'amourette' is a love affair in French, so perhaps the name was thought indelicate in France, while a lutin is an elf, or even a brownie).
The camera has a metal body, D-shaped in plan, with the lens mounted on the curved front, and the back of the camera flat. There is a panel of leather covering around the lens; otherwise the camera is simply painted. The perforated film is passed from a cartridge on the supply side to another on the uptake side, like the later Agfa Rapid system. The film advance mechanism is built into the back plate (the rest of the body, with the lens and shutter, is removed for loading). The film is advanced by pulling a tab at one end of the back, which activates a claw which pulls the film by the perforations.
Most examples seen have a 35 mm f/6.3 Double Miniscope, Extra-Rapidoptik, Laack Dialytar or Meyer Trioplan (all with aperture stops at f/6.3 and f/11.6), and a three-speed everset shutter (1/25 - 1/100 second). A camera was sold at Westlicht with a Meyer Helioplan 4 cm f/4.5 and a Compur shutter, however.
A Lutin with a 3.5 cm f/6.3 Meyer Trioplan was sold by Christie's.
There is a folding frame-finder on the top of the camera, and it has a tripod bush set in the bottom.

- The image size is reported as 31x33 mm in almost all sources, including Collection Appareils and Westlicht, but the Hungarian Photographic Museum shows an Amourette (serial no. 1319), with Double Miniscope and three-speed patent shutter, and gives its image size as 24 mm square.
