I just receive my copy from B&H.... no luck... don't have to put my ear next to it and I still able to hear. 

for people reading the date code. do you guys read it on the box or Warranty Card? the number on my warranty card starting with 042xxxxxxx... not sure if that is the right number I should get the date code from.

It's printed on the lens barrel itself.  It should match the code on the warranty card.

I've been having no luck myself.  I've tested a 042, a 072, and a 062.  All 3 make the clicking noise.  The 062's clicking is loud enough that my buddy from a couple feet away could hear it.  The 072 clicks, but worse yet it also makes a squeaking noise right as I fully contract the barrel to 24mm.

I am curious: Is there anyone who has decided to keep a copy that clicked, and found that the clicking disappears after a couple of weeks of use?  If the clicking eventually disappears after a certain amount of twisting and/or time, I might just keep one of the copies (this lottery is tiring).  If there's anybody who kept a clicking copy who is still experiencing the same amount of clicking after a couple of weeks of use, please let me know too.

this is what I am debating myself now. i bought mine from B&H and I got it shipped over to California. It would be a hassle to return/exchange it even they offer free return shipping. Back and forth will definitely take at least 2 weeks and the images I took from the lens are so sharp and colors are beautiful.  Urggg. Such a tough decision

I have a clicking on my lens. Didnt notice it on the first week, but now I can hear it if its really quiet. I cut out the upc already from the box. So I cant send it anymore for a replacement.

My 042 has a quiet tick, but my 072's tick is significantly louder such that you can hear it from several steps away.

Just wondering if anybody has kept a ticking copy who has noticed the ticking sound going away after a couple of weeks.  Basically wondering if there's like a "break in" period where after enough use the sound just goes away.  This thread has been open since June, so I'm wondering if anybody can comment who's kept a ticking lens for a while.

Data point, got my 24-70 II today from the BuyDig $1899 blowout sale (net price $1599).
Date code 082 - lens is quiet, sharp, and needs no micro AF.  Sweet deal on an amazing lens.

Is it more like a sizzling sound?

If so that might be the sound that I have heard from a few of my previous Canon lenses.

It's the sound made by the FPC (Flexible Printed Circuit) that connects the aperture controlling unit to the lens electro board.

In normal circumstances that FPC should be fixed or glued so that it does not move along the interior of the lens barrel when zooming, which pushes the aperture controlling unit up and down.

But in some cases that FPC gets loose and it starts to scratch the lens barrel, making a sizzling sound. If this is the case, then there will be the risk that it gets worn and breaks internally, especially under cold temperature.

A seasoned camera repairman told me about this and recommended me always have this issue fixed. I've had two cheap zoom lenses broken (aperture won't converge) and needed the FPC replaced.

Though I'm not sure about L lenses - maybe they are built tough and this becomes a non-issue?  Also the cable making a sound might not mean that it is touching the barrel. Maybe the cable is just tight in new lenses and needs to be stretched. 

Here's a picture of some FPC used in lenses.

Found this thread some days ago since I was about to get this lens and I got worried about this problem.
I decided to get it since there was a good return policy and the price was great with the canon cash back.
Just got my 24-70 f/2.8 L II yesterday, a 082 and luckily the lens seems to be all good.
There is a really quiet click (more like a springing sound) just after the 24mm zooming in but it is so quiet you have to get your ear right against the barrel to hear it.

Hope this helps, registered to this forum just to post this :)

Just got the 24-70 from BH. What a magnificent lens it seems. I cannot hear any clicks but I am also half deaf so don't bother anyway as long as the lens produces great pictures.

hi guys,

Just find this thread few a minutes ago. I bought these days a 24-70 2.8 II having the discussed issue: when rotating from 70 to 24mm the zoom ring produces a clinck clinck clinck sound.

exactly like this :(

Canon 24-70 f/2.8 II Zoom Ring Clicking Noise

everyone watching this movie could confirm?

What's your date code? Mine, purchased recently, begins with 042 and has the exact same issue (tick tick noise when zooming from 70mm to 24mm). In addition the left side of the frame seems to vignette a little more than the right side which could be sign of a decentered  element. Testing so far, most focal lengths seem reasonably sharp at f/2.8 except 24mm. I think that's contrary to what is expected from good copies of 24-70L II.

Shame on Canon. At this price there's still so many copies like this out there. I tried a Tamron 24-70 VC before this and had none of this nonsense. So much for L quality. This one's going back.

hi,

052xxx I think is mine. Optically is fine, sharp enough at 24mm and other focals. No vignetting on left side at 24mm whatsoever.

The sound is the only problem. We have an explanation from Canon or...silence?


regards.

Well damnit guys.


I think Im just going to have to wait a few more months until they run the $1700 promotion again.


I bought mine right before the rebates were about to end and I just received my third copy from Amazon. First was a 072xx, second was a 052xx, and this third one is 072xx. They all have a clicking noise.

The first one was BARELY noticeable, however, the focus ring felt too smoothe and could actually hear the ball bearings rubbing against something. These last two copies I recieved just had the clicking noise. Its annoying especially when doing video.

I think Ill just wait until it goes on sale again and buy it then. Hopefully by then these copies with the problem will be out of inventory. =[ Im surprised other canon forums (pot.net) doesnt have a running thread about this issue.
