The iPhone comes with a competent camera out of the box, but it could be better. We've seen a set of the third-party lenses called the iPhone Lens Dial that provides all kinds of creativity options for photographers, but it's a little on the large side, and probably not something you would want to have on your phone all the time.
The WoW Lens offers a wide angle lens that increases the iPhone camera's view by 30 percent, a macro lens for close-ups, a polarized neutral density lens to improve image quality and create motion blur effects, and a cameo mode for optical vignetting – in addition to the default iPhone lens.
The device is designed is such a way that each of the five options is easy to access with a simple rotation of the carousel. The outside of the wheel is exposed, so only the users thumb is needed to rotate the device and choose the function appropriate for the shot.
The case sporting the lens wheel measures 13.7 mm (0.55-in) deep, which is only adding about 4 mm (0.16-in) of depth to the iPhone overall. The actual lens carousel is just under 4 mm deep.
