GoPro, Inc. (formerly Woodman Labs, Inc), is an American manufacturer of action cameras, often used in extreme-action videography.
The GoPro cameras are the ultimate for capturing wide-angle action in a very small form factor. Underwater, they can capture a field of view of 127 degrees! The only limitation is its minimum focusing distance of 12 inches. Frame your subject any closer than 12 inches and your footage will be blurry.
