With its lightweight, weatherproof case, the 820 is perfect for beach holidays and sports. The 5x zoom gets you closer to the action, although you'll need to pay £181 for the mju 830 if you want image stabilisation to reduce zoom-induced blur. Both cameras have lots of other welcome features, including face detection and Shadow Adjustment Technology - a simple but effective way of capturing more detail in bright and dark areas. Otherwise, image quality is decent, but there's a three-second gap between shots, and video at the top quality setting is limited to 10-second bursts.
