Olloclip

For a lot of people, the iPhone is now their most-used, if not full-time camera. But no matter how good Apple makes the optics inside, it's still limited to the built-in lens. Unless, of course, you have an Olloclip ($70). Recently updated for the iPhone 5, this ingenious 3-in-1 lens system slides overtop of your iPhone's camera, giving you fisheye, wide-angle, and macro lenses, all in a single little package. It comes with a carrying bag and caps, but odds are you're going to end up leaving it on your phone a lot of the time.
