Yashica TL Electro-X
The Yashica TL Electro-X was produced from 1968 until 1974. It was the first camera with viewfinder electronic lights for exposure information (miniature lamps, not LEDs), and also the first with a mechanical shutter with step-less electronic timing, which operates at any intermediate speed between 2 seconds and 1/1000th, giving excellent exposure accuracy.
Two lights in the viewfinder indicate over and under exposure, and point towards the direction in which the lens aperture ring should be moved. Adjusting either the aperture ring or shutter speed dial until these go out indicates that the correct exposure has been set.
