According to “Kodak History” site this 126 film cartridge camera was produced from 1968 to 1971. The retail price at that time was $38. The Instamatic 314 has a Kodar 41mm, f8 lens and two shutter speeds of 1/40 of a second and 1/90 of a second. It has an "electric eye" and a switch for focusing from 2 to 6 feet, and beyond 6 feet to infinity. It takes the regular flash cubes that need an outside power source to fire. It uses two PX-825 batteries that have many replacements today. They are inserted into a compartment on the back left of the camera just below the viewfinder. A button on the bottom, which can be rotated with a coin, locks and unlocks the battery compartment. The flash cube socket rotates with each through of the thumb single through frame advance lever. The camera also has a film view window as a frame counter, optical viewfinder, ¼” 20 thread tripod mount, and a handy carry strap.
