The Pentax Optio S40 is an ideal camera for travelers -- its tiny body makes it a cinch to carry, and its AA batteries can be easily replaced anywhere in the world. Though the body of the Optio S40 is slightly larger than that of Pentax's other Optio cameras (its dimensions were increased to accommodate the AA batteries), it is still a remarkably small camera that makes a great companion on any adventure. The S40 comes equipped with a 3x optical zoom and a movie mode with sound.
