You must eb very lucky in that case.
My first one was decentered badly, the second had very bad vignetting, the third one was kinda ok, but PF was rather bad, and CA was there till F/2.8 - F/4 or worse, depending on the lighting conditions. And I really found it not very great wide open or close to wide open. Needed to stop down to F/2.2 to F/2.5 at least for acceptable results.[/quote]
I was lucky as well. Only one copy but without any problems whatsoever other than wide open CA, which didn't trouble me much. Sharp as tack from f/1.8 onwards, superb AF, small, cheap, what more could I have asked? In fact, [url="http://forum.photozone.de/index.php?/topic/795-next-pz-lens-test-report-sigma-af-85mm-f14-hsm-ex-dg/page__view__findpost__p__7312"]the 85/1.8 is my dream 85mm lens[/url] and if I'd feel the need for a 85mm lens I wouldn't hesitate to buy another copy.

I had a 28 F/1.8, 50 F/1.8 Mk I and 85 F/1.8 setup for low light photography, originally. The 85 was by far the worst of this little setup. The 50 Mk I was good, the 28 was very good.[/quote]
Talk about different copies. I had the same setup and my rating would be the exact opposite i.e. 85 > 50 > 28.
