EOS-1D X Firmware 1.2.1 in the Wild
By| January 21, 2013
New firmware for the EOS-1D X coming?
We’re getting various reports that serviced Canon EOS-1D Xs are coming back from service with firmware 1.2.1 installed.
There is no breakdown of what has been fixed or added to the camera, but I do expect to see an official release soon.
