The modern zoom lens for 35 millimeter photography has a focal length range extending from the wide angle to telephoto, potentially replacing several single focal length lenses or zoom lenses of small range as the standard photographic objective. This recent development appears to be the result of a continuous design evolution; each new design widening the range of power change utilized by the particular configuration. When a particular configuration is extended too far, the lens design necessary for aberration correction becomes complex, and a new configuration is developed.
