Apparently, some buyers of the new Canon EOS-1D X cameras discovered their DSLR is running on Firmware Version 2.0.7 even though the Canon USA website shows the latest version as 2.0.3
A few days ago, other buyers of the new EOS-5D Mk III also discovered similar events. Is is not unusual for new cameras to have the latest firmwares on them so Canon may be announcing new Firmware for both cameras soon? The replacement for both cameras will be coming out this year and Canon has extended the $800 rebate on both models till the end of January 2015. Check back for the latest information.
