LensAlign/Sigma 17-50 2.8 OS

Just to give everyone an update. I returned the Sigma 17-50 to B&H for a different copy. They were very good about it and I had no problems. The second copy is excellent. LensAlign yields +2 at 17,21,28,35, and 50mm. The lens is very sharp, on par with my Nikon 35 1.8. I'm glad I made the exchange.

Thanks for the help.
