Digital vs. Optical Zoom

Optical Zoom

  • The focal length changes
  • Zooms in without losing resolution

Digital Zoom

  • The focal length doesn't change
  • The image just enlarges on the particular zoom spot and loses picture quality.

See the example below.

Please note this camera in regular view.
