I've noticed an update to the EOS 1D Mk2, it's now at version 1.2.2. It reads:-
This firmware update (version 1.2.2) includes the following additional functons and improvements:
1. When pressing the DISPLAY button immediately after shooting, the LCD monitor would turn completely white, the camera would hang, and the images in the buffer memory would be lost. Countermeasures for this issue have been incorporated into this update.
2. Errata in the German and Russian language displays have been corrected.
Anyone know if fix 1 is to fix the 80x problem?
