An IS version of this lens (24-70 f/2.8) has been rumored for many years, but I don't think it is the best candidate for the extra lens elements and electronics required. It is already pretty fast and IQ does degrade ever so slightly with the extra glass. Just taking a swag at it I'd say the IS adds between 3 & 6 hundred to the retail price of a lens.


Personally I bring flashes if I think light will be an issue, or at least a tripod. And BTW if they do come out with one I will happily pick up the non-IS version for the best price yet!
