Used as an equivalent to Long Lens, but for those who wish to be overly exact, a telephoto lens is a long lens that is physically shorter than its focal length.
This is the focal length that gives you the narrowest angle of coverage, good for bringing distant objects closer. (i.e. 100mm, 200mm, 500mm etc.).
