No IS on a new 24-70? Although, I wouldn't be surprised given they released 16-35 II well into the IS era in late 2000's without
IS. But I figured that's a wide angle zoom, probably used more in landscapes and wider scopes, with likely more light, so sorta makes sense to skip IS, to keep price/weight down for the function it is supposed to serve.
But 24-70mm is a different beast that will find use in event photography, indoors, wedding, and low light situtations ... IS would be very handy...
But Canon could do what they did with 16-35 II again without batting an eye and release a non-IS version in 2012!.
I will never understand Canon marketing I guess.
