Digital Camera & TerminologyDigital Camera & Terminology Optical Zoom versus Digital Zoom
Sometimes known as "telephoto" or "true zoom," optical zoom works like the zoom on a traditional film camera. Elements within the lens move, reducing the field of view and making the object appear closer.
With digital zoom, the camera takes a small portion of an image and uses mathematics to artificially restore the file to its original size. Unfortunately, digital zoom also reduces the resolution of an image.
