Clarifi for iPhone 3G + iPhone 3GS - White. When fine detail matters Clarifi's built-in lens gives your iPhone's camera a little more optical muscle. Clarifi's lens slides into place to add detail in close-up photographs then slides out of the way for normal photography. Without Clarifi iPhone will focus clearly on an object about 18 inches from the lens. Add Clarifi and move in to about 4.1 inches for crisp detail and great pictures. This slim durable polycarbonate case gives complete access to power switch headphone jack volume controls and touchscreen and features Griffin's trademark EasyDock design; the case bottom slides off for quick docking without having to remove your iPhone from the case.
