Query: Excellent but...

This filter is well made and the rotation of the polarizing element is smooth and flawless, however, while it "fits" on the Tamron 200>500 zoom lens I purchased it for, it does not allow the lens hood to be attached and so should not be sold for that lens. I was able to return it for full credit and purchased the Sigma AF11960 EX DG 86mm polarizing filter instead and that filter fits and allows the lens hood to be attached. Note that the Tamron lens has its own filter ring rotation element.
