Yep, you read that right.  A zoom lens for the iPhone.  For only $15, the 4.69 ounce lens can add 6x to the 2-megapxel camera.
Not exactly the classiest-looking device, but hey, if it works, it works.  Personally, I’m surprised its only $15. . . seems that nothing these days is only $15. . . .

There is an example photo taken using the same lens with a motorola camera phone mount instead.  Its a little hard to tell the quality because it was shot through glass, but at least you can get an idea of how far 6x zoom can go towards giving your camera phone much more versatility
