Olympus Trip AF 31: The Olympus Trip AF31 is a compact, motorized 35mm camera. It has a built-in flash (with "Fill-In" and "Off" buttons), a built-in lens cover, a timer feature, a wrist strap mount, a tripod socket (located next to the battery compartment), and a date-printing feature. Be careful not to accidentally trigger the camera's motorized rewind feature, which is activated by a switch next to the film counter. The camera's exterior is black with white lettering. It requires two regular "AA" batteries for the built-in flash and motorized film advance/rewind, and an additional coin-style CR2025 battery to power the date feature. The CR2025 is a common and relatively inexpensive type of battery.
Olympus Shoot & Go "R": The Olympus Shoot & Go model R is a medium-sized, lightweight point and shoot camera which uses regular 35mm film and two standard "AA" batteries. Unlike cameras with electronic shutters or motorized film advance, this camera can be used without any batteries (except for the flash). Its features include red eye reduction, a built-in flash, a lens cover, a film type window, and a wrist strap. There is a three-position switch on the front which allows the photographer to select ISO 100/200, 400, or flash. Photos taken with it are generally of good quality. The back door is opened by pulling up on the rewind knob and pulling at the edge of the door at the same time. It can be somewhat difficult to get open - try using a small, flat screwdriver to pry it open. Overall, the Shoot & Go R is a good-quality, inexpensive, easy-to-use camera.
