New Scientist has this article up about new developments in lens technology. Using two different fluids and some electric current, scientists at Phillips Electronics have created a lens with no moving parts. Initial purpose will be for things like DVD writers and phone cameras.

Unfortunately they can't create lenses larger than 1 cm in diameter, so those of us who are "big glass" photography fans (people who like big zooms and telephotos) are still stuck with mega-buck monsters we can only dream about.
