Optical Zoom Focal length is the distance between the center of thelens and the image sensor. By moving the lens fartherfrom the image sensor inside the camera body, the zoomincreases because a smaller portion of the scene strikes the imagesensor, resulting in magnification.

Which is better telephoto or zoom lens?
