telephoto lens vs. zoom lens
noun
- a lens constructed so as to produce a relatively large image with a focal length shorter than that required by an ordinary lens producing an image of the same size: used to photograph small or distant objects.
noun
- (in a camera or motion-picture projector) a lens assembly whose focal length can be continuously adjusted to provide various degrees of magnification without any loss of focus, thus combining the features of wide-angle, normal, and telephoto lenses.
