The EF 24-70mm lens is a wide-angle to normal lens made by Canon. The lens has an EF mount to work with the EOS line of cameras.

This lens has excellent contrast, color rendition and sharpness. It is nearly on par with Canon's professional prime lenses except that it does exhibit some barrel distortion at the wide end of its zoom range.

A lens favored by many professionals, the 24-70mm f/2.8L has replaced the 28-70mm f/2.8L as the top EF mount lens in this focal range.

A unique aspect of the 28-70mm f/2.8L and the 24-70mm f/2.8L is that they extend as they zoom toward their widest range. This in itself is uninteresting, however when paired with the supplied lens hood (which attaches below the extending portion of the lens, allowing the lens to extend through the hood), this extension results in a perfectly matched hood from telephoto to wide angle. This is in sharp contrast to the standard zoom lens hood that is designed for only the widest setting and therefore provides less-than-ideal shading for any other setting along the zoom range.
