So I would like to add to this post, just received mine at work. I am in a normal office building with HVAC running and IMMEDIATELY, I knew there was something wrong with the zoom. Zooming in to 70mm sounded find, but zooming out to 24mm I noticed clicks. Thinking I was going insane, I did it several times hoping it would go away. It did not. So like many and not so many others on here, I was one of the unlucky ones. Batch number is 032xx. I hate to go thru the hassle of returning so Im deciding if i can just live with it and then do an RMA towards the end of the warranty period. (Im betting that I will receive another 032 replacement anyways)
Anyone who has the clicks, any word on IQ? And also, I shipped it to my work. Anyone did the same and is/are having issues with Canon rebates?
You paid such a hefty sum and you're willing to live with imperfection? You're too nice a customer. Try another seller.
