I'm throwing this out to all Canon users. I've just sent a 17-85 Canon lens for repair to Canon. It was only 4 years old and 2 things were wrong with it, a diaphragm and the motor. I was unhappy that a well looked after (and relatively expensive lens) only lasted 4 years. I have tried to have this repaired for free, arguing that its only 4 years old. Canon want 52 off me.

What are the thoughts of others?
