S/N 9029891 purchased online from B&H last week is my second and this one is going back also. Not as bad as the first but a very poor image everywhere but the center, especially at f16. I may try a third but this is all very disconcerting.
S/N 9029707 bought from KEH last week.
Brick wall test: not as impressive as I'd hoped.
Significant vignetting and barrel distortion at 16mm, even more than 16-45 lens, but sharpness acceptable throughout.
After some fairly rigorous tests, I can say that lens: SN 9032916 is in perfect working order on my K20d. I got a good one on the first shot! It's a truly fabulous short zoom, and fun to use. No regrets on getting this one!
SN 9029429 is good optically, but the zoom ring gets much tighter from 28-50. Is this common? It bugs me and I'm considering sending it to Pentax when I can be without it for a while.
It was bought from Amazon 7/08
I took the lens and body with me to work at sea last time and for 3 months it was on the cam 75% of the time. I bounced it from Lisbon, all around Italy, past Gibraltor twice, then to Brussels, Rotterdam, Amsterdam....that kit has been hot, cold, fogged, hot and wet, cold and wet, rained on, snowed on...I had ice form on the edges of the filter during Nov in Rotterdam.
Great stuff. The lens looks new, the body has a few scuffs and I've absolutely no prob's with either yet.

Yes, this is normal from what I've read. It's because there are two zoom barrels, and the second is engaged around 28mm
