The Olloclip gives iPhone 4/S users one less reason to carry a DSLR, combining a fisheye, macro and wide-angle lens in one package. Made of sturdy metal and available in red or black, the device easily clips onto the corner of the iPhone. The fisheye lens is good for panoramas, while wide-angle mode doubles your field of view. The macro lens is so good we use it to compare smartphone screens up close.
