Just some days ago a screenshot of the upcoming firmware update for the Canon EOS-1D C showed up. We reported that the firmware update is undergoing field-testing. I have also been told that the firmware update for the EOS-1D C is set to be released immediately after NAB 2013.
Now it appears that there are some issues with the release candidate of the firmware update. The issues are said to be related to the use of external HDMI recorders: users have reported corrupted frames when externally recording the uncompressed output signal taken from the HDMI port.
There is no exact information about when the firmware update should be released, but it is expected for late April or beginning of May.CR]
