How disappointing, you have deleted my comment, so I have to post it again:reviewed January 4th, 2011
I find the comparison to the way cheaper Sony's 250$ lens extremely uninformative when Sony's 800$ G lens of roughly the same coverage is the real competitor.
Choosing to compare this lens to the cheap one is totally unhelpful, as if someone is contemplating between the Sigma and alternatives on Sony's cameras, he would probably like to see a comparison against the 800$ G lens. For that matter you could have compared this lens to a UV filter and it would have been just as useful to a Sony user.
Please do not delete this comment, even though it is criticism.
