That must be a killer setup for low-light!

Precisely my sentiments on IS with wide angle. So, if you ever do pick up a CS Canon, just pick up a used, original 17-50 then.
Quote: Pentax Poke: Maybe that is not it because when I look at it, the Tamron with VC drops off in edge sharpness where the original doesn't. Could it be the optical element used for the VC?
I am not knowledgeable enough to answer this, though I wish I were. It boggles my mind why Tamron would mess with such a good thing.
