Video at Amazon.com View In this short video you can see how the rubber pad can look for the focal length setting after some time. For this I have to say that my lens was sold as a return and in very good condition. About the picture quality to others have indeed left out in detail here. Update Meanwhile I have when packing to return really an original Amazon account found, from the 8.Sept. Of 2009. Therefore can some explain now. Under Retour apparently everyone understands something different. But for this circumstance, I really do not want to be held liable, the Tamron. The one star gets it for me for a measly Gummiummantellung, something I would not even have after 5 years hanging on a lens.
