Nikon One Touch 100 brand_Tetenal this viewfinder also works wellThe Nikon One Touch 100 is a very, very simple autofocus point & shoot camera: turn it on, push the button, and a picture happens. There's a self timer, and a focus lock switch for some reason. But if you want to turn off the flash? No, the One Touch 100 flashes when it wants to, because it's an adult. In good cosmetic condition, with some surface wear. Runs on a pair of AA batteries (included) or a CR123 battery.
