Sigma DC 17-70mm 1:2.8-4.5 Macro Question


New Member
I own a Sigma DC 17-70mm 1:2.8-4.5 Macro, which I love.

But I bought this lens before the OS version came out.

Does Sigma have a trade up program?

Also, is the new OS version as good as my current version?

I purchased the OS version and waiting delivery.

I am very impressed with my non OS version, so I hope to have similar results with the OS version.
I will post my impressions after I receive my new lens.

What were your impressions with the OS version of the lens?
The lens is reported to be one of the best standard zooms made by SIGMA.


Check also the new "Art" version. I think dpreview said that it shall be slightly better then the predecessor...

But if I were you, I would wait until you get more infrmation about the upcoming 18-200 contemporary zoom. Sigma only announced that it will com ein 2014. No exact date and no price is yet available.

Best wishes
