Sunny, I just sent my 1DMKII into repairs for same issues you are having. I did purchase a second body (1DMKII) and use it with same lens as the camera in the shop. HUGE difference. The new purchased camera suffers from NONE of the issues my other camera has. The other camera is coming back from repairs and will test it. I don't know what kind of repars they did but do know (NOW) that there was something wrong. I had asked advise here on FM and tried everything I was advised to do, to no avail. I finally just sent it in and was using my wifes Digital Rebel. If you can send it in, I would advise you to do so. I got tired of the same issue you are having. Just my experience and adivise

same here. send it in.
i had three different 1d3 bodies that needed to be fixed. one had to be sent in twice. keep on canon and when it does get fixed you will love this body.
my last 1d3 i sent to canon they told me it would cost over $200 to repair. i politely told them i need to talk to their supervisor. the next day they sent me an e-mail that it would be fixed for free.
I just dropped it off today at Irvine, both the camera and lens. lets see what happens. I wasn't going to leave the lens since it's wicked sharp on the other bodies (1dsIII, 5dII, t2i) but then i remembered i had the 70-200 F4 IS that i can use to shoot this weekend on the FF body.
Thank you for the support and advice on the issue. we'll see what canon service dept says.

Just a thought. Your shutter speeds are really slow on the first three (which are also the worst OOF-wise), particularly for the lens being utilized. Might be motion blur/camera shake. Also, in the second picture, there isn't much for the camera to focus on in the low contrast area shown. Can you replicate this problem when the camera is mounted on a tripod or at faster shutter speeds?
I agree... in the first one, your focal is 200mm and the speed is only 1/125, so if not on a tripod, there is high chance of hand blur which in my opinion is the case here.. You should have been at least at 1/200..... rule of the thumb for speed...
Not a comment on Sunny, who may well have an adjustment issue with camera or lens, but that last example photograph demonstrates an issue that I often think about when others lambast this or that AF system on some camera. The issue is that some people (again, not speaking of Sunny here) forget that the best AF system on the planet cannot tell what you were thinking it should focus on when multiple possible AF subjects appear in the scene. The camera really only has two choices:
1. It can select the subject under one AF point and focus on it. The problem is that with a large number of active AF points it could be any of the many subjects at different distances from the camera and the odds are against it being the right one if you leave it to the camera to decide. (Using a single AF point can help.)
2. It can attempt to compromise between the different subject distances that are detected by the multiple AF points that activate. In theory, if the aperture is small enough, the DOF could permit subjects at different distances to be "in focus." The problem is that nothing may end up in optimal focus, since the compromise AF distance is not actually on anything. In old school "DOF calculation" terms, everything is "within the DOF," but when we magnify everything to 100% we discover what was always true - that DOF is not the area in which everything is "in focus," but rather is the are in which "things may be not too fuzzy."
