Which UWA? Need some advice

I am looking to pick up an UWA angle lens to complete my zoom kit. I have the DA*16-50 and the DA*60-250, now I need the really wide end and I'll have a three lens kit that covers everything.

I am looking at:
Pentax DA 12-24 f/4
Sigma 10-20 f/3.5
Sigma 10-20 f/4-5.6
Tamron 10-24 f/3.5-4.5
Sigma 12-24 HSM II 4.5-5.6 (not released yet)

Cost is always a factor but not the most important. I want excellent image quality and a lens that matches in with my existing kit.

Is the extra 2mm between 10 and 12 worth it? Or is there enough distortion at 10 that you shoot at 12 anyway?

Is the constant aperture either f/3.5 on Sigma or f/4 on Pentax worth it?

Any and all thoughts and opinions are welcome. I've never shot with anything this wide so I really am at a loss to determine which one to get.

I would get the Pentax DA 12-24 f/4 from B&H before they increase the price of it. currently $730, supposed to go up to $900 soon with the price hike. this is apparently one of the sharpest UWA out there.

then again, I think some people will say that the extra 2mm is a huge difference.

I have the Tamron 10-24 and love it, but then again, cost was a big consideration for me, and this lens is not as sharp as the others. But for the price and depending on your UWA needs, it may be "good enough."

edit: you said you wanted IQ to match your current zooms. You should definitely consider the Pentax 12-24.

I would recommend the Pentax, if you can find it at a reasonable price. I don't think the extra 2mm is really that necessary, and yeah, the constant aperture is nice IMO.

BTW, that splashproof Sigma 12-24mm isn't coming out for Pentax, it turns out.

I had some great luck with the Tamron 10-24 and I do know the Sigma 8-16 also is really wide too! Also, from personal experience the Sigma is FF usable from 12mm on, and from 8mm on with a little cropping, and the Tamron from 13 or 14mm on, though with a film Pentax the Sigma 8-16 is manual focus. I don't know about the rest, but that's something to keep in mind if you want to also mess with film or are waiting for the mythical Pentax FF. Both have great IQ too.

Thought about that briefly but I have another FE and don't really like the effect. Just looking for the best UWA. We have a trip to Yellowstone planned for this fall and from I read an ultra wide is needed to get some of the best shots because you stay on the boardwalks and cannot back up far enough.

Well, that is disappointing. I had that one high on my list except that the price would be quite high as well. But it is getting good reviews on other mounts. I think the big draw was potential FF ability but not sure if that really matters to me anyway, just hate to not have the option.

The 8-16 is the way to go if you do not require filter threads. It fits well with a 17-50 normal zoom for coverage with minimal over lap.
