Craig, do you think a firmware fix would resolve this, in other words, would it be a hardware or software issue?
My guess is we'll be just fine. It's an all electrical interface between the lens and the body. So I'm thinking firmware can fix this one. No big deal. Enjoy the 5D III.

Naw - if you are a Canon shooter stick with your gear. This is nutt'n. They'll fix it. And it looks like only two lenses so far at most.
As long as a firmware fix will do it. The 200 F2 is on my bucket list of lenses and I nearly bought one a few months back and the only body I owned was the 40D. IMHO the 200 F2 deserves a better sensor than the 40D, so here I am with a 5D3 that I would one day like to mate with the 200 F2.
I just dropped 5k (taxed out) for the 5D3/24-105 kit and if there is any question about future compatibility, I may return it while I can and go the used 5D2 route.
Get a nice 5D Mark II for very cheap now. If you need something faster FPS or better AF, add a nice used 7D to the 5D II...still cheaper than the 5D III.
My main concern is that Canon will figure out that it's a hardware problem and won't want to have to start with the whole "blue dot" business. So Canon will say it is normal, even though it might be somewhat bad for the lens.
I can see the engineers saying "yes, it makes a bad noise, but it doesn't seem to be hurting anything as far as well can tell." But nonetheless, after long term use, bad noise = bad things happening to the lens.
Are there other problems with other lenses? Back to a question posed earlier, why just certain lenses? Maybe there is something happening with the other lenses, only more subtle?
"...equipped with a new focus tracking algorithm, AI Servo AF III supports an even greater variety of subject movement..."
That leads me to believe that it is software related however I am no lens guru. I would love to hear Roger from LenRentals of Craig from Canon Rumors weigh in on this.
I have the 200/F2 on my bucket list of lenses and even though this is not resolved yet, I decided to keep the 5D3 and my return window has now lapsed. FWIW, I am confident this will be resolved via a firmware update.

I'm on the other side, I have the 200 F2 and won't buy the 5D3 until this issue is resolved.
Given the similarities with the AF system on the 5D3 and 1DX, I can't help but think this issue will plaque the 1DX too unless they find a fix prior to release.

Maybe this is one of the reasons for the delay of 1dx release? I just hope they make sure this issue is fully resolved before start selling the 1dx...

But you don't know that it's the AF system. It could be anything

You're right - it could be anything but it stands to reason it would be the AF system as it controls the Servo action of the lens.
(waiting for the 1dx to come and push the 1d4 price though)
