CANON 24-70 MM EF MOUNT L USM F2.8 High Image Quality and Bright.
The Canon EF 24-70mm standard zoom lens does what many pros thought couldn’t be done–it replaces the L-series 28-70mm f/2.8 lens with something even better. The lens offers extended coverage to an ultra-wide-angle 24mm, making it ideal for digital and film shooters. The new processing unit makes the autofocus (AF) faster than ever. And thanks to the two aspherical elements and a new UD glass element, the optics are far superior to the earlier lens.
