Olloclip iPhone Accessory
This bite-sized gadget is a three-in-one lens system that clips onto the corner of your iPhone. You’ll find a fisheye, a wide-angle and even a macro for your #artsy close-ups. The three lenses are optimal in camera mode but can also be used to shoot video. For the avid iPhone photographer, it’s a must have.
The Cons: You have to remove your case to attach.
