Sigma AF 70-300mm f/4-5.6 DG OS (FX) - Review / Test Report
22 July 2012
Conclusion: The Sigma AF 70-300mm f/4-5.6 OS is an attractive lens on paper, less so in the field, though.

Distortions are moderate and on average for such a lens, vignetting is well controlled and no issue slightly stopped down.
