The iPro Lens System is designed to enhance the built-in photo capability of the iPhone 4 and 4s models with an additional Fisheye and Wide Angle Lens. All the components are designed to work together, creating a portable and easy to use conversion system. The set up is adaptable for both left hand and right handed configurations, and centers around the customized iPhone case and the bayonet mounting system.Easy Installation and UseSimply attach the customized case to an iPhone 4/4S, and secure either the Fisheye or Wide Angle lens to the bayonet mount with a simple twist. The handle attaches to either the left or right side for vertical capture, plus it stores the lenses when not in use and enables attachment of the iPhone 4/4S to a tripod. Fisheye and Wide Angle LensThe Fisheye delivers a true image, with results that are distorted in all the right ways by a field of view converted to 165 degrees. The images produced are both panoramic and dramatic, with results that exceed any app.The Wide Angle converts to a 35% wider field of view with minimal distortion and edge-to-edge sharpness. The expanded view is ideal for capturing groups of family or friends, a small room or even large crowds.Precision Made Optics and HousingBoth lenses are made to ensure the best possible images, with precision housings machined from aluminum alloy and anodized for durability.The elements are ground and polished from high grade optical glass, and receive a multilayer anti-reflection coating.The iPro Lens System is a convenient option for producing first generation images from the iPhone 4 and 4S, as opposed to using an app.
