Best Buy Customer Reviews

Did not work1 Posted by: from: on I have a Canon EOS Rebel XTi and these did not work for this model. The camera was unable to focus with these tubes I was unable to use the focus ring on manual and the lens did not focus when on Auto. The lens I used for these tubes was my Canon 50mm 1.8 II lens. The package and reviews were poorly noted since it did not say which cameras were compatible and looking on DLC's page I sent a message and I had no response on which cameras they were compatable with.
