The Tamron 10-24 is interesting. On paper, it seems superior to the Sigma 10-20 and even the Pentax 12-24. But most reviews tend to be disappointing. Then again, the few people we've heard from who actually own the lens seem to love it. I've love more reliable information on the Tamron.
nope, it's not superior against the Pentax 12-24. and it's colors are smudgy, probably the reason why some people don't like it. but resolution-wise, I think it's quite up against the Sigma or better on average.

here are the strengths and weaknesses of each lens.

Pentax 12-24: strength: great resolution
weakeness : horrible CA

Sigma 10-20: strength: CA is well-controlled
weakness: more pronounced distortion

Tamron 10-24: strength: distortion is well-controlled
weakness: smudgy colors

Here you go:
Over at lenstip.com you can find reviews for both the Tamron 10-24 and the Sigma 10-20 (but the new f/3.5 HSM).

On the 12-24, one of the easiest items to correct in software is CA. I have not really experienced bad CA with my copy (or possibly the situations where I tend to use it). It is the sharpest lens I have - discounting the FA 31 Ltd. The problems with the Sigma and Tamron are somewhat less controlled. The distortion is fixable in software as well, but the 12-24 construction is better along with its sharpness and resolution. I also tend to gravitate to the Pentax colors. Also, yes both of them are wider, and 2mm at this range can be significant (but its still less than 5 degrees FOV), however I have found that for me, the 12-24 is about the widest usable range. If the 12-24 does not handle it, the 10-17 at 180 degrees will, and there is nothing available rectilinear at 0 or 1mm (the 10mm FE equivalent).

Things are stitchable unless they are dynamic and in motion. If a single image on the 12-24 is not suitable, then shoot multiple panels. If that does not do it (or is NOT possible), then the 10-17 will surely take care of the situation (even through a 360 degree pano).
