Canon service advisory for EOS-1D X and 5D Mark III cameras

Canon recently put out a service advisory for their EOS-1D X and 5D Mark III DSLR cameras. I have copied the advisory as can be found on the Canon USA website below.

Affected Products

EOS 5D Mark III Digital SLR Camera
EOS-1D X Digital SLR Camera

Details

Depending upon the shooting conditions, it may take slightly longer for the EOS 5D Mark III and EOS-1D X digital SLR cameras to acquire focus when using the Speedlite's AF Assist Beam, compared with that of the EOS 5D Mark II and EOS-1D Mark IV digital SLR cameras using the Speedlite's AF Assist Beam.

We are developing a solution to enhance the focusing feature for the EOS 5D Mark III and EOS-1D X and plan to release a firmware update based on following estimated schedule:

• EOS 5D Mark III: (estimated) Late April, 2013
• EOS-1D X: (estimated) Late May, 2013
