optical zoom
On a digital camera, optical zoom is a true zoom feature. It allows you to zoom in (or out) on the subject in the LCD or viewfinder. This will enable you to get a closer view of the subject before taking your picture. Optical zoom changes the magnification of images with the actual optical glass before the images reach the imaging sensor. Optical zoom allows for better photo quality than digital zoom.
