Firmware on schedule
The scheduled release of the EOS-1D C firmware for April is still probable.
I received a screenshot of the firmware being tested a few days and just got around to it today. The screenshot shows all the various frame rates available to you for the EOS-1D C. The biggest addition is the ability to record in 25p at 4K resolution.
We’re told it’s going to be available after NAB. Speaking of, we’ll be in Las Vegas next week for NAB checking out the latest in video gear.
