Interresting about the color shift. I inevitably tweak the WB when processing raw files, bu thaven't noticed any lenses with consistent color shifts. The only other Sigma glass tha ti use much is the 70-200 f2.8, and I haven't noticed any color shifts with it...

Mark, if you get to buy a Sigma, I will be most curious to know how you'd compare the color rendering of both lenses. Initially I did not notice it, but Tamron 28-75 and Sigma 24-60 yield different colors - Tamron being the warmer and Sigma being a bit odd for I lack words to describe it in a way that would make sense. The best I can do is say that it seems to eat up a bit of yellow and that general aspect of rendering is a bit lifeless. Not terribly so, but still... May be since introduction of Sigma 24-60 they did improve on their coatings a fair bit, I don't know but I'd certain want to hear your opinion on the matter if and when you get a Sigma.
