We've had our hands on Canon's latest zoom, the EF 24-70mm f/4L IS USM, for a couple of hours and prepared a quick preview. It's clearly designed primarily as a 'kit' lens for the EOS 6D, but of course will work just as well on Canon's other full frame bodies such as the EOS 5D Mark III, as well as APS-C cameras on which it will offer a 38-112mm-equivalent range. In our preview you can read more about the lens and its features, including its unusual macro function, and see how it compares in size to Canon's other L series standard zooms.
