Digital cameras are compact and portable, yet have great functionality. Top of the line cameras have advanced lenses, more than a 3.0x optical zoom, and 10.0+ megapixels for clarity of picture. Some mini cameras have HD video recording, touch screens, image stabilization, face detection, and long battery life. When you buy a camera you should also consider one that is waterproof. Digital cameras are essential for saving the moment, then sharing it with family and friends. Sony and Canon have the best picture quality, but Olympus makes a cool waterproof camera that also takes high quality pictures.
