I still have my sigma 8-16 for APS-c. I was all excited there for a moment.
I don't think anyone has a 10-20mm zoom for full frame. I know folks use the Sigma 10-20, but they have to do some cropping to get it to work. Personally, I think the 15-30 is wide enough for normal purposes and has relatively mild distortion considering how wide it is. If you need wider, I suppose one of the Irix primes is the way to go.

Who knows? The 24-70 and 15-30 are both listed as "SDM" lenses, but clearly they have a different motor from any of the DA * lenses. Even the individual DA *lenses have different motors from each other.
Hopefully Pentax hasn't chosen an under-powered motor just to make a slightly smaller lens.
