Dear friends, just a simple question:

Is the 1DS Mark III affected by AF issues?
Anyone is using this camera for sports? (With good results?)

Thanks for your comments!

Mine isn't. But then I don't shoot much sports, and what I do generally isn't at fast frame rates.

In my opinion, it is. But it is used more in studio (thus shooting more frequently at f/8 than at f/2.8) and so it's not as frequently reported.

I do have both bodies, and have seen focus issues with the 1DsIII at aperatures less than f/5.6 in studio.

There are no AF problems with mine, but I only shoot moving wildlife, not sports.

Use my 1dsIII mostly on static subjects such as landscapes,
cityscapes and some studio work.

I've not noticed any autofocus problems using it for these subjects.
Used it at a recent airshow and the had no autofocus problems.

I used my 1Ds3 for about a month while my 1D3 was in for repair, and shot a couple weddings and a couple PGA tour events, didn't notice any AF problems like my 1D3 had. Of course my 1Ds3 was manufactured after Canon had issued the "fix" for the 1D3, so this was to be expected.

No AF issues at all.
Used it for many sporting events.

I find it to be quite good. Just posted some football shots here.

There were reports of the AF locking on to a more contrasty area even if it was noticeably far from the focus point - in one shot mode. Quite a few people said they had seen it.

Mine is great, but I don't shoot sport. The latest firmware upgrade definitely made an improvement to jitters in servo though.

No problems here with AF (although I may not use the camera for subjects where the issue might arise)

I shoot fast moving dancers in low light. The 1Ds Mk III's AF works fine-even from F1.2 to F2.0. However there are, occasional, lens AF calibration issues which can be addressed with micro AF.

Mine is one of those - but it only manifests under f/5.6 (or at least, is only noticable) - but I have a hunch it has to do with the difference in using cross-type AF points that engage at that point.

I have found my 1Ds2 to be better for BIF than my 1Ds3. On the other hand, my 1Ds3 is far better at everything else (mainly very low light Servo), and so for me it's a win.

I owned a 1Ds3 that was plagued with random and weird mis-focus issues at all apertures, with all my lenses and all AF points. It drove me nuts. Canon swapped it for another one that is free from the aformentioned issues. What else is there to say..? The 1Ds3 AF has its strengths and weaknesses...
