This camera was introduced in 1988 and discontinued in 1993. From the Kodak S-series point-and-shoot line, the S100 featured a (plastic?) 35mm f/4.5 lens and 3 aperture settings. The camera required 2 AA batteries to power the flash but was otherwise a manual camera. The aperture was set by way of either the "film speed" switch (100/200 or 400) or by the flash switch. The smallest aperture was used with the film speed switch set to "400" and the middle aperture setting was used when the switch was set to "100/200." The aperture was the most open (f/4.5) only when the flash switch was enabled. However, if the photographer removed the batteries, the camera could still be used with the flash switch enabled, thus giving 3 different aperture levels. The camera also has a built in lens cover that locks the shutter button when closed, a frame counter, optical viewfinder, right thumb film advance wheel, fold down rewind crank that pulls up to release the film, rewind film release button on the bottom of the camera body, flash read light, and a film view window in the back cover. The camera was made in Taiwan R.O.C. (Republic of China) and distributed by Eastman Kodak Company out of Rochester New York.
