The Minolta Electro Shot was Minolta's first rangefinder camera with CdS meter controlled exposure. An electronic circuit with 6 transistors and 3 diodes transforms the metered EV into appropriate control signals for the camera's electromagnetic shutter device. Thus a kind of exposure program delivers appropriate speed/aperture combinations. Control rings around the lens barrel are for distance and film speed setting, and a third one for switching from automatic mode to the guide number of the flash gun. Then aperture will be set appropriately for a flash exposure with shutter speed 1/25 sec., depending on distance and film speed setting.
