Fujitsu has released the F705i handset in Japan, with claims that it is the slimmest waterproof phone currently available. The ultra-thin phone is just 13.7mm thick. The handset is designed to work even after being immersed one metre deep in water for half an hour. The F05i features a 1.3-megapixel camera and a quick zoom function which adjusts the size of text on-screen with the touch of a button. The phone also features Super Clear Voice and Super Clear Mike features, which adapt the call volume to suit the background noise conditions when making a call. The F705i measures 106×49x13.7mm and weighs in at 111g. It provides 170-minute of talk time, or 100-minutes of video calling, on a single charge.
