The FUNCTION SELECTOR RING has three positions: "B" (for bulb), a lightning-flash symbol (for using flash), and "AUTO. " At the "AUTO" position, the shutter speed control is fully automatic.

Selecting the diaphragm setting moves the diaphragm leaves to the desired f/ stop. At the same time, the diaphragm setting ring selects a value of resistance for the exposure control circuit. The shutter then automatically programs the shutter speed according to the amount of light striking the CdS cell, the diaphragm setting, and the film-speed setting. The fastest speed the camera can deliver is 1/500 second.

As you start depressing the release button, watch the indicator lamps on the top cover.

If the red (overexposure) lamp comes on, you know that the fastest shutter speed of 1/500 second is too slow for the proper exposure. You must then set a smaller f/stop.

If the yellow (slow) lamp comes on, the required shutter speed is too slow for a hand-held exposure (slower than 1/30 second). The yellow lamp warning tells you to use a larger f-stop, a flash attachment, or a tripod.
