The Camera-Lite is a simplified successor of the Echo 8. The Echo 8 was marketed in the United States from1951. Initial interest was modest, but sales leapt when the camera that was used in the 1953 movie, Roman Holiday (1953, Paramount Pictures). Roman Holiday starred Audrey Hepburn, Gregory Peck & Eddie Albert. Eddie Albert, playing a photographer, uses an Echo 8 lighter camera to get candid shots of Audrey Hepburn (incognito princess being tailed by various heroes and villains) for a scoop story by Gregory Peck (reporter).
The Echo 8's appearance in the film stimulated demand to a level that the Suzuki Optical Company could not satisfy. In response, in 1955, the company produced the more affordable and simplified Camera-Lite. It has a fixed focus 17mm f8 lens and only an instant shutter speed. The neat reflex viewfinder was also removed and you have to hold the lighter to eye level to use the sports finder. It is more easy to spot, as a camera in use, than the clandestine way of using the Echo 8.
