I have owned this lens almost from the day it was introduced in the U.S. It has a lot going for it--excellent construction, quiet focusing and a very useful zoom range. Between 17-50mm focal length, it is about as good as you could ever hope a zoom lens could be. The trouble begins above 50mm, where the image is soft at infinity focus, even stopped down to f8. This is not to say that the lens in unusable between 50-70mm. It probably can hold its own against similar lenses, e.g. the Sigma 17-70, which many users like. But if you are a fanatic about IQ, as I am, you may not be fully satisfied.

I have the DA star 16-50, but I much prefer this lens. I have had this on my K7 for a few months, and I find it a near perfect all around lens. Fast, quiet focus. Fairly fast constant f4. Great build quality. Excellent sharpness throughout zoom range with no apparent optical flaws in real life photos. A great lens that has me looking for a buyer for my 16-50.

It's big and heavy, but it takes great pictures on my Pentax K-7. The SDM focus is fast and quiet. The zoom operates silky smooth and there is no "zoom creep".
