So, I would stay away from that lens.


I think the newer copies of the canon 100-400 have much better QC. Certainly one of the reasons I avoided considering the 100-400 was all the stories of bad copies and break-downs but pretty much all the threads I have seen lately say the newer built ones are much better. There was even a few who had tried the 100-400 again after several years and concluded that "something" different had been done to the lens. Sounds like maybe Canon actually listened to all our griping and decided to fix the problems. If they have tweeked the assembly line to iron out the bugs, and the lens still sells like hotcakes, then it seems unlikely they would upgrade it any time soon.
