|Canon EOS-1D X cameras|
As I have reported in my earlier post, Canon USA has now officially acknowledged the Speedlite AF assist beam issue on EOS-1D X and EOS-5D Mk III cameras.

Depending upon the shooting conditions, it may take slightly longer for the EOS-5D Mk 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-D Mk II and EOS-1D Mk 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 Mk III and EOS-1D X and plan to release a firmware update based on following estimated schedule :
EOS-5D Mk III : (estimated) Late April, 2013
EOS-1D X : (estimated) Late May, 2013
