Canon calls this the CANON ZOOM LENS EF 24-70mm f/2.8 L USM. EF means "electronic focus," meaning that there is an autofocus motor in the lens itself. All Canon lenses since 1987 have been EF.

The EF 24-70mm f/4L IS USM is the perfect zoom to complement full-frame DSLRs like the EOS 6D. With 2 aspheric and 2 UD elements, the EF 24-70mm f/4L IS USM delivers high-quality images with excellent detail throughout the entire zoom range. A 9-blade circular diaphragm delivers beautiful, soft backgrounds.

Second the Canon EF 24-70mm f/2.8L II USM Lens is the best zoom lens made. Better than anybodies, even brand-N ! I know for a fact personally since I have both. It does cost quite a bit but the best usually does. The Canon EF 24-70mm f/2.8L IS II is the kind of lens pros put their trust in. There are sharper lenses, lenses with better bokeh, and lenses with broader zoom ranges, but the 24-70mm f/2.8L offers a finely tuned mix of usability, flexibility, performance, size, price, and durability.
