Can the owners of this lens comment on the IS noise? I have 5d Mark III and I am aware of the recall but based on the Canon service bulletin, my lens should be fine. Bulletin says lenses with a serial number where last two digits ends with 00, 01, and 02. Mine ends with 03 plus it has a date code of March 2013 so its a pretty new lens and should not have this issue.
The noise I hear is the IS engage/disengage sound and it is a bit louder than 70-200 IS II. It is a very audible 1 click sound. Once IS enables the remaining sound is the regular gyros moving which is fine. But the initial click and the end click is loud. Is this normal?
The box that the lens came in was in a fairly bad shape so I am a bit scared the lens may have been damaged. But then its in that massive case and I see no issues with IQ or viewfinder images.
