Watch the Nikon Coolpix p900 camera zoom into the moon. This is the first bridge camera on the market with an 83x
optical zoom, and it sure is something. It also includes a
digital zoom, which reaches to 166x, or 4,000 mm.
What is the difference between optical and digital zoom?An optical zoom is a true zoom lens, like the zoom lens you’d use on a film camera. They produce much better-quality images. Some cameras offer a digital zoom, which is simply some in-camera image processing. When you use a digital zoom, the camera enlarges the image area at the center of the frame and trims away the outside edges of the picture. The result is the same as when you open an image in your photo-editing program, crop away the edges of the picture, and then enlarge the remaining portion of the photo.
