"The Mujjo fisheye is a great little novelty lets that's cute, small, easy to carry, and a lot of fun to play around with, especially for kids."
The Mujjo fisheye lens is an incredibly inexpensive way to try out fisheye photography on your iPhone, iPod touch, iPad -- or almost any smartphone or tablet. A fisheye lens is designed to take extremely wide-angle pictures, so wide that it becomes almost spherical for still photographs. That means, however, you can get a lot more content -- people, scenery, etc. -- into a shot than is possible with a standard lens. It also means that pictures are often warped to almost comical levels. But that's really the point.
