Serial Number: 9014888
My replacement copy is a champ!

I tested using vector-based picnic stripe patterns printed at 600dpi on a HP LaserJet 4350n. All exposures were as excellent as one can hope for in a DA* zoom lens.

Focal lengths tested: 16mm, 20mm, 28mm, 35mm, 50mm
Apertures tested: f/2.8, f/4, f/5.6, f/8, f/11, f/16, f/22

Cheers!

Of all the bad images related to the DA* 16-50 that I have seen on this forum, I think I had the worst copy of the lens. At all focal lengths and apertures, my images were blurry (double images) with the exception of the center area being very clean and sharp.

Replacement was due for delivery yesterday, but my wife didn't hear UPS ringing our doorbell. I'll report back after Monday with the replacement's serial number and test results.
