While both my DA* 16-50 and 50-135 autofocused great with my K20D from the time they were new, they didn't focus properly with the K10D, although other FA and DA lenses worked fine with the 10. I sent the 10 to Pentax Colorado without the lenses, and they were able to fix it. I think some K10D's were made with incorrect calibration for lenses with in-lens motors.

The 16-50 which took some weight when I dropped my camera bag a couple weeks ago now doesn't zoom wider than about 20mm before it stops.

Clearly I busted something off and it's now gumming up the works. Darn it all, that really bums me out.

Back into the Pentax service department again.  Nuts!

On the bright side: I found (before I dropped it) that it focuses flawlessly at all focal lengths with my friend's K20D. So... someday when I upgrade I'll have a lens which I can just leave on AF even when at 16mm. Or I can live without my K10D for a month by sending them both in for calibration (shudder). Don't think I can live that long without a camera in my hands.
