Upload & Sell: On
I realize this looks like a pretty fancy image, but remember there were reports of 'several' iterations of the 24-70/2.8 II being tested. Until Canon releases the info, I wouldn't necessarily take this as gospel, however good the image appears (I acknowledge that it does appear 'real'). Also, as several have mentioned, if image quality is indeed a large step up from the original, it probably will sell like hotcakes, once the word is out, especially if it is so much lighter (the image resembles the build of the 16-35 II in many ways).
My question is this: What is the 'bump' on the top side of the image, above the distance scale (i.e. to the right of the model inscription)? None of my black L lenses have this (granted, I'm not a gear collector), but it sure looks like another switch of some sort. Lastly, the bottom edge of the AF switch that is shown looks PS'd, it just sort of disappears into the bottom of the image.
Focus limiter maybe? And Canon isn't going to make any high resolution press photos for prototypes. I think we can pretty well be assured this is a final lens.
