Hi,

I have been using an EF100-400mm L (mark I) for the last few years now (on and off) and hadn't used it for a while.

Today I took it out for a spin and noticed a serious "clunk" each time the stabiliser kicked in (and stopped for that matter).

I am talking a serious metallic kind of clunk that is very much audible and can also be felt when putting your hand around the front of the barrel!

Now I am quite sure that this clunk was not there on the past and am wondering if this is the first step in the failing process of my IS?

Do any of you, who have used an EF100-400, ever had this happening to their lens, and if so, what was the end result...?

Thanks!!

if you are so interested, send your "clunky" lens to canon repair service center and they can let you know what is wrong your lens and how much it'll cost to fix it. sounds like it'll cost a  large wad of cash to fix it so i'd be thinking and planning to buy a new 100-400 II in the near future if you want to replace your clunky lens
