Liquid lenses

Liquid lenses

According to Varoptic, liquid lenses are now ready to be used in camera phones. The company's Arctic 320 lens can both zoom and autofocus without any moving parts. Instead of being mechanically driven, the focal distance is changed by running a current through a suspended liquid between the lenses. These lenses will probably be first seen in camera phones, but point-and-shoot cameras won't be far behind. A zooming, autofocusing lens with no moving parts can add a great deal of resilience and take away a lot of weight from compact cameras.
