* Both varifocal and zoom lenses are
built with movable elements that
permit changing the effective focal
length. And the key difference between
a varifocal and a zoom lens can be
explained by thinking about a lens that
has been focused on an object at any
focal length. A varifocal will need to be
refocused whenever the focal length is
adjusted; the zoom will stay in focus
when the focal length is adjusted.
