Auto focus cameras have just replaced the old hassling ones, but are not able to pour out impeccable pictures. But now we can hope to get a perfect camera phone with fluid droplets acting as a lens giving out crystal clear pictures all the times.

A couple of scientists in Singapore have successfully tested the liquid lens, such as water droplet, that changes its focus with a slight pressure. It'll not only cut short the weight but also eats less power sparing the battery. A similar lens was introduced by Varioptic that uses electrowetting technique.
