The olloclip is a quick-connect lens solution for the iPhone 4/4S that includes fisheye, wide-angle and macro lenses in one small, convenient package that easily fits in your pocket. Nestled in the palm of your hand, the olloclip connects to the iPhone within seconds so you'll be sure to capture the image you want if you don't see the picture you're looking for just flip it over to switchlenses.
The Fisheye lens captures approximately a 180 Degree field-of-view and produces some striking images.
The Wide-Angle lens is great for when you need that extra field of view, approximately double that of the normal iPhone.
The Macro lens applies roughly a 10X multiplier and allows you to focus the iPhone within 12-15mm of the subject. The Macro lens is cleverly concealed within the olloclip and can be accessed by unscrewing the Wide-Angle lens that is normally attached to it.
The olloclip ships with a carrying bag made from a microfiber material that doubles as a lens cleaner and conveniently holds the supplied-lens caps or the Wide-Angle lens when removed for Macro shots
