Nikon has today announced a successor to its first ultra-slim camera, the Coolpix S1, in the shape of the weatherproof Coolpix S2. Aside from the splash proof features all other changes on the S2 appear to be purely cosmetic. The most obvious difference on the 5.1 megapixel camera is that it features a sliding lens. It will only be available in silver and is slightly bigger and heavier than its older brother; it will also have a different docking station (supplied). Other similarities include the same control layout, a 2.5-inch LCD, SD memory slot with 12MB internal memory and 35-105 mm equiv. zoom lens. It will be available in early summer priced around US$429 (approx €448/£299).
