Canon Service

Just wanted to plug Canon's service for a second. My 400mm was sent in last Friday to Canon for repair, the tension ring seized. It arrived at Canon in NJ on Monday and is back in my hands right now. Talk about fast service done right!! The lens works great and upon testing it out, not one dust spot!

I'm glad to hear!

Though I was confident that your lens would work well, I was concerned about it being reassembled with dust inside of it, or something that would still not make it as you sent it out.
