Yashica Electro 35 G -The first Yashica Electro 35 was introduced in 1966, it had a cold shoe and the meter accepted film speeds from 12 to 400 ASA. Light levels are measured using a cadmium sulphide photo-resistor and powered by a mercury battery. A simple twin-bladed diaphragm closes in front of the light sensor as the film speed is reduced. The light metering electronics works by accumulating the measured light level and only releasing the shutter when it has determined enough light has fallen on the film. This system allows the shutter speed to be completely step-less and to adapt to changing light levels. The metering system can keep the shutter open for up to 30 seconds. The Electro 35 G was introduced in 1968 with largely cosmetic changes. The range of usable film speeds was extended a little up to 500 ASA. The lens was labeled a “Color Yashinon” to reassure the buying public that it was color corrected at a time when the use of color film was growing quickly.
