Just buy the Olympus Tough TG-1, set it on “iAuto” and shoot. The A.I. of this small camera works very well underwater. The fast f/2 lens let you have sharp pictures even in low light conditions, at least with static/slow subjects. The additional white LED gives macros brilliant colours.
Among the very few defects, colour vibrance quickly decreases in low lights, like probably with other underwater compact cameras. Big temperature differences (hot to cold) caused condensation on lens and LCD, however both disappearing in a few minutes. Last but not least, the three screws of the protective lens are not tough at all, being already rusty after a few weeks of use.
