Canon Publishes Official Product Advisory Regarding AF Assist Beam and Canon EOS 1D X / 5D Mark III DSLR Cameras

Canon Logo
On February 6, we highlighted a Canon Forums moderator's response acknowledging the Canon EOS 1D X and 5D Mark III cameras were slow to acquire focus when using a Speedlite's AF Assist Beam. Now, Canon has published an official product advisory regarding the issue:
 
From Canon:
 
Thank you for using Canon products.
 
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
