Hi, not related, but related to the AF. I'm noticing on old lenses that the AF is sporadic, inconsistent, in short really bad. Mainly on my modified Contax lenses. I would think it's the lenses, but they are spot-on with my Mark ii. The other lenses I've tried are fine.
So there must be something with the new AF that needs to be adjusted...
I'm not sure that Canon will bend over backwards to make people's converted Contax lenses work flawlessly...

With new camera releases sometimes 3rd party algorithms fail to function correctly. I had this as an issue with an old Tokina lens and heard of the same with Sigma. The correction is most likely going to come on your side, not Canons. That means sending the lens to be flashed by Conorus. That doesn't explain the 200IS though of course...
I was seriously planning on my first outing with the 5D III be with the 200/2L. That's too funny. Oh well - I'll have to wait until my 5D III ships before I can confirm this with my 200/2L
This is very surprising to me. I would have thought that IS worked completely independently of the body, such that you could use IS on a body that was manufactured before IS was even invented.
It would seem that IS would exist entirely within the lens and that the body wouldn't care to know about it. That IS would make a different noise on a different body suggests the body is more involved in IS operation.
I wonder if it's a power problem - that the 5D3 is providing too much (or too little) power to the lens, and that's causing the IS to behave differently.
They probably didn't think to try this, but wouldn't it make sense for Canon to pay one person
to simply take each new body about to be released and go out and shoot a few shots with every
lens in their line-up? It probably seems like overkill, but it wouldn't cost that much and would
catch a lot of problems like this.
Canon will fix it, and probably quite soon, but it kind of cracks me up that they must not shoot
many actual photos with these things back at the lab.

How dare you discuss the concept of logic in a Canon thread?
I reported this issue to Canon, through "normal" channel as my CPS contact was unavailable, and support claimed I was first to report this! He said he will forward my report and they will call back.

Got an email back stating the EF200/2IS always has been "loud"... and it seems the information I gave over the phone was not entirely noted
I ended up giving all details once more, this time on e-mail and referring to this thread to show it's not just me, plus sending information to my CPS-contact through web-form.
It seems to have got them busy, as no further replies has been received
Having the same problem with the 200 f/2. Today I tried the 5DMIII with the 800 and it also was making more noise than I had heard before. Annoying enough that I would not want to use the lens with IS on. Turned off IS and everything worked well. but there is certainly some change caused by the 5D. Hard to believe Canon is not aware of this.
