Any Tamron 10-24 mm test reports?

Anybody have or tried or read any thing about the new Tamron 10-24mm lens that came out recently? I mean

besides the brochure data. I am interested in how it stacks up against the Sigma and the Tokina, in similar focal

lengths.

<a href="http://virtualentity.blogspot.com/2008/11/tamron-10-24-35-45-vs-compared-to-sigma.html">VirtualEntity</a> has a comparison with the Sigma

10-20.

<p>

He explicitly states, that he tests a hand-selected Sigma 10-20 against the only Tamron 10-24 in whole Slovenia, but even then it does not look like the

Tamron could be much of a killer lens. At least with these particular specimen, the Sigma wins by a considerable margin.

Am also very interested in this lens, but haven't seen many reports out. There was a discussion on Flickr a while back, with some photos from a trade show and then I came across this person's blog:

Been hoping that this lens would make a nice pair with the 17-50 gem. Hope others here have more info.
