These sweet little lenses for your phone give your camera a whole new life. DLSR's are very expensive these days and have a lot of features and buttons which can put off the average user who wants to simply just push a button to take a picture. These lenses will give you more to play around with and help you experiment without making your wallet feel thin.
There are four main lenses, fisheye, macro, wide angle and telephoto. Macro and wide angle use the same lens. You can buy them separately at $20 for the macro/wide angle and the telephoto, $25 for the fisheye or $49 for all them.
It's a great little addition for your phone camera. However you don't just have to use them on your phone, you can even use them on a webcam, such as the camera that comes with a Mac.

The macro detail which can be achieved from using the macro lens is quite incredible.
