If you’ve been seeing the growing options in lens attachments for the iPhone, this design shouldn’t be too much of a surprise. The iPhone Lens Dial takes a wide angle, fisheye, and telephoto and puts them on a dial mounted on an iPhone case so any lens is never more than a couple of clicks away. The ring also has holes between each of the special lenses to allow use of the regular iPhone lens.
The wide angle gives you a 0.7x view, the fisheye gives 0.33x, and the telephoto brings you in to 1.5x. The case has tripod mounts for both landscape and portrait orientation shooting, and whole package weighs only 10 oz. It fits iPhone 4/4S and will run you $250 from Photojojo.
