As people point out regularly, Canon has never done IS on any EF lens below 100mm . . . nice as it would be, why the intense surprise?
-> EDIT
Looking back, the two other rumored lenses have IS? So, we either have to believe that canon suddenly is going to go IS on their normal/wide EF lenses . . . and this one won't have it?
Something doesn't add up. Maybe Iran is behind the photos, they like photochop 
idk, IS = more weight, and 2.8 is sufficient in most situations.
having IS would of course be really nice. but the 24-70 (used to?) is really large and heavy.
I would sacrifice IS for less weight and overall size.
I mean, it's still a zoom lens, it already has a lot of flexibility.
having a 24-70 that makes the camera more "normal" is great.
and no name next to the red ring? that doesn't sound like a big deal.there doesn't seem to be space under it anyways?
