the Sigma 17-70 is regarded, with reason, as one of the best bang for your buck around town. It's optically excellent, fast, great and accurate AF, close focusing, reliable.
The new one is supposed to be a tiny tad worse in IQ but it's also faster (but with less macro enlargement possibilities). The Pentax 17-70 is supposed to be excellent, but less versatile and more expensive. If it was WR then it would be another story.
