I went to take the backpack out of the car. It was unzipped. My 70-200, attached to the body, fell onto the ground and hit hard on gravel. At least it landed on the light shield. The zoom ring is locked in the full zoom position. What now?? What is the procedure to send the lens to Canon. Do I send it to California? New York? I've been browsing the boards for about 20 minutes but I'm sure someone has a link to a thread in their favorites. If you would share that I would be appreciative.
