The camera is essentially a point-and-shoot, but you do have some control over the exposure. Once you set the ISO (ASA) dial that is integrated in the meter dial, you read the exposure value indicated by the top-mounted meter and transfer this to the exposure value dial on the top of the lens assembly, then take your shot. The camera has a fixed shutter speed of about 1/50 of a second. Adjusting the dial changes the aperture of the lens only from 12 to 16. These settings do cover most daylight conditions (from overcast to bright sunlight), which is really what this camera is built for. The Kodak Starmeter kit does include a “Supermite” flash that uses AG1 flash bulbs and it uses two AA batteries accessed with a common screw driver by removing the metal back cover. The Starmeter was introduced in April of 1960 and discontinued in November of 1965. It was made in both the USA and Canada but the numbers of them is unknown but is near a million. The camera uses 127 roll film for a picture size of 1 5/8 X 1 5/8". Some of the cameras other features are a Kodar f/8 lens, rotary shutter, built in selenium meter, screw with pins flash contacts, and the camera sold for an original price of $19.95.
