Much awaited Tamron 17-50

I am one of the apparently many who are giving serious consideration to snagging one of these when it's available. I currently have the Tamron 18-250 and it seems to be a very nice lens for what it is but I think the 17-50 will serve some needs. Please tell me if I'm wrong in this thinking about the 17-50.
1. Would be a better lens for low light with its constant f2.8
2. Given the narrower zoom range would probably have better IQ than the 18-250
3. Although not a dedicated macro would be better for macro and/or portrait photography than the 18-250.

Feel free to add your own reasons for wanting/needing the 17-50.

1. good tests, though a bit of a problem with CA at 17 mm. But that's no problem for me.
2. price difference to pentax 16-50 and expected compatibel IQ quality, despite loss of sdm and probably somewhat less built (sigma 18-50 left out of comparison cause of less favorable tests /experiences)
3. money to be saved will be put in fast 70-200 from Sigma with HSM

To compliment #1, wider aperture also means narrower depth of field whenever I want to do selective focusing or maybe even portraits. I'm trying to get out of the habit of thinking about wide apertures as "just for low-lighting."

One minor point is that my DA 16-45, the front element actually extends out several inches in wide angle, which I've found awkward a few times in really tight spaces. The Tamron 17-50's front is retracted in wide angle.

My reasons for wanting the Tamron are similar to yours, I can't wait for it to hit the stores!

Re:

Same here.

I also might add, that compared to the Sigma 18-50 F2.8 its a touch wider at 17 but with a smaller overall dimension than the Sigma.

It gets much better reviews, however. It all depends on the price difference!

Re:

Oh I meant that as a good thing. Tamron is wider than the Sigma at wide angle and yet is still smaller in size overall. (Which is preferable if you want a general take anywhere lens).

But your right the pricing for this lens will be crucial for most buyers still undecided between the two.
