The EF 28-70mm f/2.8L USM has proven very popular with professional and advanced amateur photographers since it was introduced in 1995. However, the increasing use of digital cameras, most having sensors smaller than a 35mm film frame, has increased the demand for a high-performance standard zoom lens with a wider wide-angle setting. The EF 24-70mm f/2.8L USM lens meets this need. The optical design is based on the previous lens, but incorporates new design features that allow the broader focal length range while maintaining the superb image quality. At the same time, the minimum focusing distance has been reduced from 0.5 metres to 0.38 metres.Improved water and dust resistance ensure that it will become the leading standard zoom lens in the EOS system.

The EF 24-70mm f/2.8L USM is a high-performance lens. It has been developed as a successor to the EF 28-70mm f/2.8L USM, but with a wider zoom range to meet the needs of photographers using certain digital cameras.
