I have a question weybourne. I myself also have a Canon EF 28-135mm f/3.5-5.6 IS USM and im very happy with its performance. But when i went to Canon for my annual maintenance, they told me that the production this lens is already discontinued and they eventually won't accept services for it in the near future. They even offered me a swap out discount for a newer model lens. Do you have any idea regarding this? Or is this information true in your country as well?
