This is the CASIO GV-20, a waterproof camera. It's an old camera, about 20 years old, but it's still in good condition with no noticeable scratches or dirt, and it's still usable. The lens is a 4.6mm F2.8 fixed focal length. It runs on four AA alkaline batteries. The media is CompactFlash. Although not pictured, a 65MB card is included. I tested it before listing it, and there are no problems with basic functions such as shooting, playback, and flash. Please prepare batteries. Thank you.
