To Users of the Canon EOS C300 and C300PL Cinema EOS Cameras.
We have suspended download services for Firmware Version 126.96.36.199.00 that was posted Tuesday November 12, 2013 at 8PM EST, because it has been determined that discrepancies in color balance can occur with footage captured by the EOS C300 and EOS C300PL running Firmware Version 188.8.131.52.00.
We are currently preparing new firmware with a fix for this issue and will release it as soon as it is available.
We are very sorry for the inconvenience, but we ask for your patience during this time.
We are preparing new firmware with a fix for this issue. If you have updated your EOS C300 or EOS C300PL firmware to version 184.108.40.206.00, Canon will restore the camera’s firmware version to 220.127.116.11.00 for any EOS C300 or EOS C300PL camera running firmware version 18.104.22.168.00.
