Buy the The iPhone Lens Dial at the Photojojo Store!
The iPhone Lens Dial boasts three optical-quality coated glass lenses: Wide Angle, Fisheye, and Telephoto. All wrapped up in a slim aircraft-grade aluminum jacket equipped with two tripod mounts (for portrait or landscape shots). To switch between lenses just rotate the disc! Best part: the lenses never leave your phone, so they're always at the ready. Use the 0.7x Wide Angle for sweeping landscapes or get fun warped images with the 0.33x Fisheye. Switch to the 1.5x Telephoto and get nearly two times closer to your subject. Wowza.
