Introduction November 1993 (1993-11)

The Canon EF 28–70mm f/2.8L is an EF mount wide-to-normal zoom lens made by Canon from 1993 to 2002. It was replaced by the 24–70mm f/2.8L.

Among standard zoom lenses, it is known for very good contrast and sharpness and for its extremely low chromatic aberration and barrel distortion.[1] It has a metal body and neutral color rendition.[citation needed] Although discontinued since 2002 it is still a high ranking lens according to DxOMark among Canon zoom lenses and other standard zoom lenses. Like many other zoom lenses, it exhibits some barrel distortion at the wide end of its range.

A unique aspect of the 28–70 mm f/2.8L (and 24–70 mm f/2.8L) is that its barrel extends as it zooms toward its shortest focal length. When used with the supplied "petaled" lens hood, which attaches to a non-moving part of the lens, this extension results in a properly matched shade at every angle of view. Most zoom lens hoods are designed for only the widest angle of view, offering progressively inadequate shade at longer focal lengths.
