I haven't noticed any softness issues with my 17-70c but in all honesty, I haven't taken a lot of shots at 17mm. The distortion at 17mm is quite noticeable in a lot of shots but correctable fairly easily in PP. As for whether it's better than the older version, I don't have one to compare with but it's unlikely that I would buy the new one if I already owned the older version. It is a really good lens in my experience so far. It's quick to focus and silent to my hearing (which isn't good so don't trust my word).

I assume since it is not a Pentax lens, there is no in-camera correction for the distortion.....which wouldn't be a big deal to those of us who usually shoot RAW anyway.

I haven't tried it with my cameras. Even with my Pentax lenses I don't use the in camera correction for distortion or chroma exactly for the reason you mentioned, the write speed reduction, since it's fast and easy to correct in my processing.

Your assumption is correct.

I have been shooting with the 17-70 (C) for a couple of weeks now and am pretty impressed. My only beefs are the weight and the "shortening" of focal length at moderate to close subject distance. The FOV at 1 meter and 70mm zoom is about the same as a 55mm prime.
