Have in August 2007 the Tamron - bought 4-5,6 / 70-300 Di LD to my Canon EOS 400 D Zomm AF. By May 2010, it has done best service. The then occurring defect (zoom adjustment is no longer possible) made a repair at TAMROM necessary. The correct handling with cost estimate, etc. I had accepted. The total cost incl. P was 91.04. Because now for 3 months, the lens is again defective (error message: Can not record) TAMRON request was so please send in fault isolation can be edited, answered. No, I will not do that to me. At about the same high costs as above, I can better buy a new, comparable objective. No TAMRON it will certainly not be in this experience.
