The Minox subminiature camera, in its various models, was for years the world’s most widely used spy camera. The ultra-light aluminum shell Minox A/III was produced from 1954 until 1962. Because of its small size (82 x 28 x 16 mm), it was easy to conceal and operate in one hand. It could take excellent photographs of documents at close range and was a natural choice for clandestine photography. It was also used as an espionage camera by both sides during the Cold War. It had an electromagnetic shutter. When closed, the viewfinder and lens windows are protected. Complan lens is a unit focusing lens, focusing from 8 inches (20 cm) to infinity through precision gear linked to a focusing dial on top of the camera. The camera does have a green filter that can be moved in front of the lens, but it wouldn’t be visible since the filter only goes in front of the lens, not the viewfinder. An 18-inch (460 mm) measuring chain was provided with most Minox subminiature cameras, which enabled easy copying of letter-sized documents. The espionage use of the Minox has been portrayed in Hollywood movies and TV shows. Lens: 4 elements in 3 groups, 15 mm f/3.5 Complan. Dimensions: 82 x 28 x 16 mm. Shutter: 1/1000 – ½ B, T, and Battery: None. It has “Wetzlar” engraved on it.
