I am looking for a wide angle -
From the lenses I have , I think the Tamron will be my walk around day / night lens (Vacation kinda walking) with 50 f1.7 in the bag. That should cover day/ dusk and night as best as I can.
I can live with my Sigma's 70-300mm for now - mostly wild life shots and as soon as football starts will use it then for my son in daily light does a pretty reasonable job (this is where I may buck up for a da*)
As you may have noticed in my sig I have picked up the K10D !!! now I am just as incompetent as before but with a much higher end tool
I will be selling the K100D along with the kit lens (18-55) and perhaps my Sigma 18-125 to fund a new lens at some point. (I think, still kinda thinking about it)
For comparison purposes I had a look at one online shop and my 'short list' is below. So I guess I am looking for a relatively fast , zoom that covers 10 - 28 or close to it. I could be convinced on a couple of primes or a couple of zooms I guess. I do like the convenience of zoom, and for what I do with the pictures the sharpnes seems more than adequate. The $700 is on the upper end of what I want to spend as well.
I don't think I will get the DA* 16-50 as for that kind of money I think I would rather have a longer range. The Pentax SMC 16-45 may be a contender as it is a great price and lots of good talk here, but is that allot of overlap with my Tamron ?As mentioned I would like to carry as few lenses as possible. Also is 16 wide enough ? (Rhetorical question as the come back is wide enough for what ? haha)
I guess it boils down to the Sigma 10-20 and the Pentax 12-24 f4 and the SMC 16-45. tHE 16-45 wind on price for sure the other two Price is pretty comparable but hte sigma is a full stop slower at the wide end (I can probably find it cheaper elsewhere) But that fisheye is kinda cool as well ...

For prices I am heading to Sin City (Las Vegas) in October may be able to get a btter price there - thinking of doing the Helicopter tour of the Strip , Hover Dam and Grand Caynon thus the 'need' for something wide ... plus a few trips to the moutnains this summer. Do you think the 16-45 would be enoguh ?
