Don't know about official comments, haven't heard that and usually we won't unless and until there's a service advisory released.  A friend just received his 24-70 II with the clicking noise, called Canon and they said none of their copied clicked, and recommended he send it back to the vendor for exchange.

Went to a local shop and checked out a rental copy of the 24-70 II and it has the same clicking noise, although it's a lot quiter after heavy use. I canceled my return/exchange.

Just a little puppy trying to make it in a big digital world.

I ordered one on sunday from B&H, and I am expecting delivery on this thursday as well.  I have already prepared myself for the likelihood of needing to exchange the lens.  That aside, B&H is great company and if an exchange is needed they are always a pleasure to deal with.  I will update when my lens is received.

So, the internal components that are rubbing together to produce the clicking noise wear down with use, reducing the noise?  I'm not sure that I'd take that as a good sign.   ???

It is a very good sign.
A very good sign that you now have small fine metal filings inside of your lens.

I'll be getting my replacement lens later today from UPS. I'll post back her once I get it. DPReview GearShop was nice enough to overnight air the lens to me right after I called them and discussed with them the noise. I noticed from the UPS tracking that it was being shipped from Amazon's Pennsylvania warehouse. My first was from their New Jersey warehouse. Let's hope I get a different batch as a result. Wishful thinking, perhaps.

I am getting mine tomorrow from B&H.  I am crossing my fingers, but there is a strong possibility that it will have it.  I am just curious... I know that Adorama was doing the same sale, too, but in a shorter window... Anyone bought from Adorama with the clicking issue?  What about lens from Amazon?  Is this limited to the batch from B&H?

I know of at least one (edit: one other) person who bought the lens from Adorama, and has shipped it back due to the clicking issue.

Comments like these are/is why you should NOT trust everything you read on the internet.

The clicking sound you guys are hearing is the elements 'crossing' over through the zoom range. Its normal for components to move inside a zoom lenses. (any lens for that fact) This condition was apparent in some of the 24-70mm f2.8 mkI. It does not affect the performance of the lens, nor will it have any adverse effects on its longevity.
If you are still concerned, just inform the issue with Canon the next time you send your lens into Canon Service. If your lens is under warranty, the manufacturer should be able to make any repairs stated in their policy.

When its my lens that makes the clicking noise, it doesnt bother me, because i know its a normal part of a zoom lens opperation.

Good luck everyone!

I guess that is why mine doesn't do the clicking noise and is very smooth. It is normal operation and mine must be defective and not normal.

Obviously it's normal for components to move inside a zoom lens - how could the focal length change, if nothing moves?  Focusing causes movement inside the lens, too.  But...how does that explain the silent 24-70/2.8L II lenses that many people (including me) have?  Does that mean my silent lens is defective, because it's not making that 'normal' clicking sound? (Edit: I was beaten to the punch on that question!)  How about the fact that none of my other zoom lenses make any sort of clicking sound when zoomed?  Or the fact that when asked, Canon Service advised someone with a clicking lens to return it to the vendor?

Maybe the clicking noise doesn't represent a problem for long term use, although since this seems to be pretty recent issue, there's no way to know that.  But it's definitely not 'normal'.  To anyone who wants to gamble with a ±$2K lens with a relatively short (1 year) warranty compared to the expected useful life of the lens, I wish you luck.
