Olympus takes the waterproof point-and-shoot to a new level with the TG-1, which includes a fast f/2 lens that gives it the best low-light performance in its class. It takes very good stills compared to other rugged cameras, along with solid HD video. If its 4x zoom lens isn't long enough, Olympus sells a waterproof teleconverter that bumps it up to almost 7x, along with a fisheye lens for wide-angle shots. On top of that, the TG-1 includes not just GPS but a compass and a manometer to warn you when you're approaching its 40-foot underwater limit. If you need to go deeper, Olympus sells an optional housing that increases its range to 135 feet.
