This lens is killing me

Excerpt: Optics are fantastic and no complaints there. The problem is the AF. It only works when it wants. I am on my third lens and same problem every time. Well, the first one the AF never worked, second was great and then a week later died.
Excerpt: The results are outstanding when the lens works. Unfortunately I had the SDM fail for the second time, with less than one hundred shots. The lens was used only in benign environment, never abused. At [$] per repair, it's not sustainable.
Excerpt: Sharp pictures, good colors; some chromatic aberrations at 16mm. Big problem is, that the autofocus motor died in the middle of a vacation. The lens is now off to Pentax for warranty repair. My experience, unfortunately, is in line with other users' experience in that respect.
Excerpt: using Camera: K-7 situation: inside of house with natural light/fluorescent lamp I did not expect that the length of the lens became extended as I recognized that this lens was inner focus type.
Excerpt: I tortured myself over the purchase of a high quality zoom that would compliment the focal range of the DA* 50-135 f/2.8 (I own this lens and am more than satisfied in all aspects). Another candidate was the Tamron 17-50 f/2.8.
Summary: They are still having problems with quality assurance. This lens arrived and it looked great. I took several test images of a large 2 foot square black-on-white ink line drawing. It had sharply defined ink pen lines all over it, all the way to the edges.
Summary: I was willing to get this lens because it has a DA* sign on it, which make me think it should be one of the best lens produced by pentax, however, I was wrong. In order to get this lens, I sold my 17-70 f4. This is really stupid action and I really regret doing that. It looks pretty good right?
Summary: The lens initially really impressed in build quality and the packaging was good. The moment I started shooting however it was evident the lens consistantly focussed behind the focus point. This is very dissapointing!
Summary: The built quality is exceptional. sharp, smooth and fast AF. Be sure to update your k10D firmware to v 1.3 before using this lens, so you wont be like me at first scratching my head wondering why a lens this expensive is noisy and vibrates.
Summary: Image quality using this lens is better than a kit lens, but not what I'd expect in a pro lens with a high price point. Also, this is the second Pentax DA* lens that the drive motor failed. Inexcusable.
