It looks like 1.1.1 firmware is available in Japan for the pro shooters at Osaka. Won't be available until mid-September for public distribution?
1.1.1 Firmware out for the 1d MKIII: Canon EOS-1D/1Ds/5D Forum: Digital Photography Review
John, did you have a chance to take more shots of Pippa at F2.8? As I take a better look at your shots of Pippa, most of them appear soft (but perhaps it's the resolution, my monitor, or I'm just looking too hard!?). I'm very curious to know if you get sharper results with your 70-200 at F2.8. At the very least, it would be interesting to do a comparison.
I've gotten mixed results shooting my 9 year old and 3 year old with my 70-200 IS at F2.8. F4.0 and higher seems fine. F2.8 with centre focus AI servo. Some of the shots are brilliant (incredibly sharp!) and others are disappointing - either out of focus or soft. Softness appears to be a known issue as well as OOF.
For the record, my testing is with a 529xxx body. My OOF isn't too bad, but most of my shots are soft. I would normally suspect my 70-200 2.8 IS, but I'm also getting some brilliant shots with that lens as well. Weather conditions for testing was bright sunlight, hot and humid - 90 deg.
Finally, here are some comments I posted on another forum regarding my recent conversations with Canon service here in Eastern Canada:
"I spoke with the Canon Service facility for Ontario yesterday morning. The 1st person I spoke to mentioned receiving the tools and parts from Japan necessary to fix the AF problem. He then said that I should speak with the 1-800 Support number first. I called Support and found them to be useless. I called the Service Facility again, got someone different, and they didn't know anything about "tools or parts". They went off to talk to someone for more details, and then told me to call Support. I waited until the afternoon, called the Service Facility again (hoping to get the first guy) but then got the same run-around as above. In both cases, I strongly felt as if they knew a whole lot more but weren't allowed to provide any details other than follow the standard script "check this, check that, call them, bring it in, etc.".
My sense is that there are a few issues - some but not all people affected by "faulty" hardware or hardware that needs "tweaking" and other issues requiring another firmware update.
I also get the strong feeling that the Techs and Reps are being muzzled by Canon. Sure, some of the techs are ignorant to the problem, but when they go off and speak to someone about it, they come back on the line.... sounding different somehow. My paranoia? Perhaps. "
