Canon announce another AF accuracy advisory for EOS-1D Mark III and EOS-1Ds Mark III

From Canon UK Consumer Product Support today:

We have learned that some EOS-1D Mark III and EOS-1Ds Mark III digital SLR cameras have a problem in the accuracy of the AF (autofocusing) feature.

If an AF point other than the center AF point is used, focus may become soft.

Free AF accuracy checks and adjustments will be provided to affected products. Please click here to complete a registration form if you own an affected product and wish to arrange for service. After you have submitted the form you will be contacted by a representative of a Canon Service Centre within one week for a service appointment.

A prior registration and appointment is preferred before sending your camera to Canon. Any cameras received without a pre-registration and appointment will be serviced at the earliest possible opportunity.

Supplementary information:
Based on the comments and suggestions of professional photographers, we have also created supplementary AI Servo AF information (AI Servo Auto Focus Manual) for users to fully utilize the AF capacity of the cameras. Please refer to this information when you shoot with the EOS-1D Mark III and EOS-1Ds Mark III cameras.

Previous information regarding AF (Auto-focusing) with EOS-1D Mark III and EOS-1Ds Mark III:
The following web announcements were previously released to inform users about improvements in the AF accuracy of the EOS-1D Mark III and EOS-1Ds Mark III.

We offer our sincerest apologies to customers using these products who have been inconvenienced by this issue.
