Just 18mm thick, the G2’s all-metal body makes it one of the slimmest and lightest cameras on the market. Eight-megapixel resolution, 4x optical zoom, 4.5x digital zoom, aspheric all-glass lens, 2.7” high-resolution, indoor/outdoor LCD screen make it hard to resist. But so do advanced features such as Smile Detection, Blink Detection, Face Detection and In-Camera Panorama Stitching. Rechargeable Lithium-ion battery.
