    Details
    Depending upon the shooting conditions, it may take slightly longer for the EOS 5D Mark III / 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 / 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 / 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
