Fisheye lens (fish-eye) is a unique perspective. A photographic effect that creates a fish eye perspective and leads to years of creative fun. This lens is sort of like a wide angle but instead, straight lines become curved ones, like clouds may just start blossoming and swelling in your photo. It can make your pictures more powerful. Encased in a luxury aluminum exterior the lens is made of fine glass. You can use the Gizmon Magnet system for easy installation because your toy camera(s) will all enjoy, their new found freedom.
