Iphone Lens Dial
The iPhone comes with a pretty good camera, but with the Lens Dial you can give it a huge upgrade. It boasts three optical-quality coated glass lenses: Wide Angle, Fisheye, and Telephoto. The case itself is made of slim aircraft-grade aluminum adding 280 grams to the iPhone (compatible with models 4 and 4S). It has two tripod mounts, a vertical for portraits and a horizontal for landscape shots. source
