IPCS Word(s) of the Day: Optical Zoom
June 23, 2008 by Garrett Smith
Optical Zoom= Changing the focal length of a camera by adjusting the physical zoom lens. The higher the optical zoom, the better the results. In a camera, an optical zoom of 10x or more is called a “superzoom” lens. Note that if a camera is advertised with “10x zoom,” that does not necessarily mean optical zoom only. In many cases, the optical is 3x with the additional 7x being digital.
