There are plans to release an EF 24-70 f/2.8L IS sometime in the next 18 months. I have confirmed from two sources that the end of 2013 or early 2014 is the earliest we’d see a production model announced.</p><p>There are no plans for a non-IS 24-70 f/4L.
It's not a surprise that Canon has been researching this. However, a fact that has been flogged repeatedly on these forums is that Canon is out to make money, not just produce great gear. Is it really cost-effective for Canon to support both of these lenses? Either this is targeted to the video crowd (supposing strong sales of the non-IS Mk II to the stills-only crowd) or the Mk II isn't selling well enough. If the problem is lack of Mk II sales, then maybe the IS model would replace the Mk II. That would be weird, though...
This just doesn't make sense unless they had delays with the IS version, and felt compelled to release the non-IS Mk II as an interim solution.
It's all just idyll speculation (pun intended) on my part since I can only dream about lenses too expensive for my hobby budget.
