This camera is similar in specification to the Instamatic 804 but the automatic exposure on this camera is provided by a CdS cell rather than the selenium cell of the 804. Although this makes the system more responsive in low-light situations, it is also dependent on batteries, whereas the selenium cell is not. A small button is fitted below the viewfinder, adjacent to the lens, which is used for testing the battery and the "Use Flash" lamp in the viewfinder doubles as a battery confirmation. Flash is provided by flashcube socket that turns with each shutter release. The camera has an Ektanar f/2.8 38mm lens that contains thorium oxide and is, in fact, radioactive (one of many Kodak lenses from the 40's, 50's, and 60's that share this attribute). The shutter has speeds 1/60 of a second, 1/125 of a second, 1/250 of a second, and B that are set with a dial on the front of the camera. The camera also has an optical viewfinder, rangefinder, ¼” 20 thread tripod mount, strap attach points, frame view window on the back cover, and spring motor film advance that is wound by pulling on a long nylon strap that rewinds into the camera's bottom. The camera was introduced in 1968 and was produced till 1970. It used the 126 cassette film cartridge and the camera list price at the time was $139.50 in the US.
