The Register has this article on liquid lenses for camera phones. Those lenses are designed and built by a French company, Varioptic and are really cool. Because they use a combination of water and oil, they can change shape, which means that the focal length of the lens can change without any moving part, a bit like the human eye does. As a result, you can have auto focusing lenses that fit into something a few millimeters thick and use much less power than a traditional lens. The ideal solution for a camera phone. And they reckon we might get the first models in the shops by 2006. I want one of these!
