Most digital cameras are only part-timers. Why? As the day wears on, their batteries start to run dangerously low, and their low-light performance is beset by image quality problems. The F10 Zoom, with its new Real Photo Processor, is the exception. With a 500-shot battery life and an incredible sensitivity range that stretches from ISO 80 to 1600, the FinePix F10 Zoom is a camera to be used at any time of the day or night.
