Q. Canon has also released new firmware for the EOS-1Ds Mark III, and it includes what sounds like the same autofocus changes as the new firmware for the EOS-1D Mark III. Is that because the EOS-1Ds Mark III has the same autofocus characteristics as the EOS-1D Mark III?
Yes. While we haven\'t published anything about EOS-1Ds Mark III autofocus to date, we\'ve used the high-resolution camera extensively since mid-December 2007 and can say that its autofocus strengths and weaknesses echo the EOS-1D Mark III.
