Beyond the Pentax Optio WG-1 GPS cameras already available in black, purple or yellow/green comes a model so colorful that in water you might mistake it for an orange ruffy. But we’ve yet to meet a fish that could register its own latitude and longitude. Or switch on an array of five LEDs from its face to get a close-up view of a small sea star lurking in the shadows on the sea floor. Or be so rugged as to be shockproof, crushproof, dustproof and waterproof to 33'. (Okay, that last feat shouldn’t be much of a stretch.) Available in early July, the orange Optio will offer the identical capabilities of its less-colorful cousins.
