This camera was introduced at 1971, but before there were some other variants of this model, which were the Olympus 35 EC/ RC/ ED/ RD. It only works in automatic exposure and with preset combinations of shutter speed and aperture! It comes with a F.ZUIKO 40mm f/1,7 lens!
The only problem is that you can’t shoot during low light conditions. The hot shoe allows the usage of flash in a particular way as well: you tell the camera what is the guide number of your flash unit and, as you focus your subject, the aperture is set according to the distance!
