The S-30 is an autofocus point-and-shoot camera for 35mm film, introduced by Japanese manufacturer Ricoh in 1989. It is also known as the Shotmaster AF in the United States. A version with a data back was also available and it was sold as the S-30 Date.
This camera was designed primarily to meet the market demand in developing countries; there was a growing demand for an affordable, simple, but not-too-small camera, especially in the Asian markets. Hence this model was relatively larger than more feature-laden cameras of the day, e.g., AF-50, XF-30D etc.
It was a very simply made camera. It has an auto-focusing system which uses only three focusing zones. The shutter runs at a fixed speed, and the aperture is set according to the film it loads, regardless of the light conditions it's in (e.g., always F8 when ISO 100 film is loaded). The flash does not activates automatically, the low-light warning LED informs the need for flash, and the operator follows it.
There is a fixed-focus version named L-20 which has very similar specifications to this model.
