The two on both ends are reusable plastic cameras with a plastic lens, fixed focus and f-Stop. So they are for outdoor with good sunlight. The middle one is awesome automatic camera with a great lens by Carl Zeiss. The only annoying thing is the flash is always on when you first turn on the camera and then remember to turn off the flash. It auto loads the film and winds it to the first frame, reads the code on the film canister to set the ISO, and rewinds it back when the roll is finished. Just aim and press the shutter release button. The only manual control is the flash. I bought it a long time ago as a backup camera
