What is it: This rugged, weather-resistant 2-megapixel model has a sporty vertical design that encourages one-handed shooting.
Why you need it: It's plenty fast, portable, and easy to use, and it's primed for a splashing good time. For a 2-megapixel model, it does quite well with exposures, whether you're above the water or under. And as long as you're down there, rock out with the Oceanic DV-128.
