Clarifi's no ordinary polycarbonate case. That's because when the details matter, Clarifi's built-in lens gives your iPhone's camera lens a little more optical muscle. The lens slides into place for macro and close-up photography, then slides aside for normal photography. Without Clarifi, iPhone will focus clearly on an object about 18 inches from the lens. Add Clarifi and move in to 4.1 inches for crisp detail and great pictures. Case constructed of polycarbonate with access to power switch, headphone jack, volume controls and and features Griffin's EasyDock; remove the case bottom to charge and sync, put it back on when you're ready to go.
