This is an Olympus μ-Tough 6020 waterproof camera. It has a 5x optical zoom starting from 25mm and is waterproof up to 5 meters. After the earthquake, we didn't have enough cameras at work, so I used this one on-site. I used it two years ago when I went diving in Okinawa, and it worked perfectly. I hadn't used it since then, so I fully charged the battery and tested it by taking pictures and playing them back, and it seems to be working fine. There are many fine scratches overall, but there's a protective film on the LCD screen, so it should be in relatively good condition if you peel it off. The AC adapter for charging is made by Nikon. Thank you.
