Neither update is particularly special, no new features or anything like that. But there are some notable *fixes* for both cameras. Specifically, the list of changes for the EOS-1D X is much longer than the 5D Mark III.

Both cameras had improvements made to their AF performance when shooting in live-view with a wide angle lens. Apparently, the cameras had issues with that in the past, but this new firmware resolves those problems and improves the AF performance in LV. You can get the full list of changes to both cameras below.
