Canon Product Advisory For Speedlite AF Assist Beam Issue on EOS 5D Mark III and EOS -1D X

Speedlite AF assist beam

Ok, Canon reacted to the problem of the auto-focus beam issue observed using Speedlite AF assist beam with a Canon EOS 5D Mark III (price & specs) or Canon EOS-1D X (price & specs). Everything started when a user posted about the problem in the Canon USA EOS forum, getting the following answer from a forum moderator (I reported about this here):

Canon has confirmed that, 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 firmware update to enhance the focusing feature for the EOS 5D Mark III and the EOS-1D X. The schedule for release of this firmware update will be announced shortly.

Yesterday Canon USA released the following product advisory:
