Quora User, Digital photography since 2003... Optical zoom is a variable focal length lens, like a 15-85mm or 25-200mm lens. In an APS-C sensor DSLR camera, the standard or prime focal length is 35mm. Any focal length lower than this is called wide angle range. All the focal lengths above 35mm are called tele photo range.
3x optical zoom and 5x digital zoom are standard features on most mid-range pocket digital cameras. A better optical zoom capability would be 6x or 8x optical. A 4x optical zoom creates images on the sensor or film that is up to 4 times larger than when the lens is at its wide-angle (unzoomed) position. A 6x zoom goes up to 6 t â¦ imes larger (or, if you prefer, closer).
