We're hearing from a large and growing number of photographers this evening that Canon USA's customer care centre is advising EOS-1D Mark III owners who call in that a fix for the camera's AI Servo autofocus problems is approximately two weeks away, that it will involve replacing the sub-mirror (a mirror behind the main reflex mirror that passes light to the autofocus sensor module) and that customer care reps are taking down contact information from those customers who would like to be notified when the fix is available.

 

Update, October 18, 2007: We've updated our June 19 article analysing EOS-1D Mark III autofocus performance with official comment from Canon.
