From a Q&A with a Canon spokesperson:
Q. What is the fix that Canon has developed?
A. A hardware fix. Specifically, a component in the camera called the sub-mirror must be adjusted. The sub-mirror - also called the secondary mirror - is a tiny mirror behind the main mirror that passes light down to the autofocus module in the base of the mirror box. The adjustment procedure may include the swapping of one or more parts that make up the sub-mirror mechanism, though the sub-mirror component itself will not be replaced.
Q. What EOS-1D Mark III autofocus problems does the fix address?
It's meant to solve poor AI Servo focus prediction when tracking a moving subject, particularly in warm-to-hot shooting conditions and particularly when shooting bursts of pictures.
------
So basically Canon has confirmed what Galbraith and others were saying right from the beginning, and cameras that are affected will now be fixed, which is good news for shooters.
Thanks for the link. Glad to see that Canon is acknowledging the problem.Quote:
