The E840s is an intermediate eight-megapixel camera that could be mistaken for a premium model. Its lightweight, ultra-slim 19.5mm body holds a 4x optical zoom, 4.5x digital zoom, aspheric all-glass lens and 2.7” high-resolution LCD screen that’s auto adjusting for indoor and outdoor lighting. Advanced features such as Smile Detection, Blink Detection, Face Detection, and In-Camera Panorama Stitching are also packed into its tiny body. Rechargeable Lithium-ion battery.
