Three-in-one lenses are so last year, the Olloclip 4-in1 Photo Lens promises to make you snap happy with its collection of fish-eye, wide-angle and a couple of macro lens options. A cinch to use, it simply slides over the corner of your iPhone and offers a 180-degree field of view. Weighs less than an ounce, is scratch proof and the tough metal-like finish is yours in a choice of red, black or white.
