Originally posted by Pentax Bob I noticed in the lens data base that there are 3 Sigma 70-300 mm lenses listed with 3 different ratings. I am very interested in the highest rated one. It is identified as DG OS. I have searched the Sigma web site and not found any reference to this lens. Is this very new or is it perhaps a mistake. It sounds like a great upgrade from the Tamy 70-300 macro I now own. Is there some way to distuinguish this lens from the other two?? Your help would be much appreciated.

Did you notice the one that has the highest rating only has one review? in other words, one person calls it a "10"...i bet if you look through the other variants you will find one person who called each of those a "10" as well. just sayin'.
I did own two of these Sigma zooms and enjoyed them both...good luck with the hunt!
I just noticed that the thread for yet a 4th variant, the 70-300 DL, has been moved and they took my photo of it and used it for the APO version reviews.
