Ah yes, the Olloclip. One of the original truly successful Kickstarter projects that helped breathe some life into the iPhone photography craze. They've been hard at work over at Olloclip, creating a number of different lenses for different phones, and now even the iPad. The 4-in-1 is the latest update to their original lens, the 3-in-1, and it appears to be better than ever.
Snap the Olloclip on the corner of your iPhone 5, 5s, iPad Air or iPad mini and you'll end up with 4 new lens options. A wide-angle, a fish-eye, a 10x macro, and a 15x macro. They're all incredibly fun, and it makes iPhoneography infinitely more interesting.
The Olloclip comes in five colors: black, red, gold, white, and space gray. The lenses are all precision ground multi-element optics, and the barrels are machined from aircraft grade aluminum. The clip is made from soft plastic, so it's easy to get on and off and will not scratch or mark your precious iPhone.
