[QUOTE="LensWork, post: 81572, member: 1283"] This is a common misconception. "Zoom" lenses are by-and-large not true zoom lenses, but rather are technically vari-focal lenses. Virtually all "zoom" lenses must be focused (refocused) after you zoom to compose your picture. The term "zoom" lens has been generalized to be any lens that offers a variable focal length, however a [U]true[/U] zoom lens is one that maintains focus throughout the zoom range and this type of lens is very rare.
