wide angle zooms for α100

[woodsman]

I currently have two wide angle zooms for my α100: a Sigma 24-70, f2.8 EX DG and a Tokina AT-X PRO 20-35 f2.8, both of which provide fine images.  Can anyone suggest a wider angle zoom of similar quality? I've looked at Tokina, Sigma and Sony for options and current offerings seem to be all slower and/or unavailable in the Sony (aka Minolta) mount.  Any suggestions would be welcome...

Sigma has a 10-20mm and 12-24mm.

Stoped down the Tamron 11-18 Digital lens is ok if not particually fast.  Your in a tough situation so some compramise is going to be necessary.  I checked their website and it states it suports the Sony/KM mount.

I've linked a brief review over at Nikonians.  They looked at 4 super wide zooms (Inc. the Tamron) from a Nikon perspective.
