Moment, known for its line of high-quality lenses designed for the iPhone, recently came out with its newest lens, a 170-degree 14mm fisheye lens that works with Apple's iPhones, including the newest triple-lens models.

Fisheye lenses are by definition ultra wide-angle lenses and are some of the widest lenses you can get, often offering up a wide view with artful distortion to capture as much of a scene as possible.
