Nice shots--I have no problems with mine wide open either.
Oh, neat...thanks!! Those were just some getting to know the lens shots when I bought it last June.

Good to read you had no issues either. I have owned or used over a dozen different Sigma lenses and not a single one of them had any apparent focusing issues. No front or back, no overly soft focus just nothing. The only issue I had was the one I mentioned and that was when the AF to infinity focus broke. Still I could use it in MF mode if needed. And Sigma fixed it quickly with no HoyaTax of $19.95 (I think this might just be for service under the 2-yr extended warranty though) for daring to send in a lens for warranty repair.

FYI, to all in general, Amazon now has a price listed for the Sigma 10-20mm f/3.5. It is priced for preorder at $649 with free shipping. Sigma 10-20mm f/3.5 EX DC HSM ELD SLD Aspherical Super Wide Angle Lens for Pentax Digital SLR Cameras: Camera & Photo

I will wait and not order. To me the speed is not as important in an UWA lens. And, to me, I doubt it is worth a $200 premium over the current f/4-5.6 version.

I'd love a 10mm rectilinear lens at 2.8, but doesn't seem they make it. Don't quite trust Sigma's 10mm prime 2.8, but that's a fisheye however...heard a lot of complaints with sigma in general wide open and even a stop there after.

Any good manual lenses that are 10-12 primes at 2.8?
Don't expect to find such lenses. Ultra wide angles aren't bokeh territory though, and very hand holdable, so large apertures aren't really necessary.

I have wet dreams for the Sigma 12-24 on full frame. Equivalent to 8mm on aps-c, rectilinear. DROOOOL
