No actually I was thinking about the "confirmed by Canon" future update to
EOS R5 from the original CR posting. Post has no source mentioned, and I haven't seen it mentioned elsewhere. But a later comment gave the answer (plus also promise of update to
EOS R6 too) :
www.canon-europe.com
In addition to the EOS R5 firmware version 1.1.0, Canon is already working on
further future updates in response to feedback about the
EOS-1D X Mark III and
EOS R5. Canon plans to introduce the following video recording functions via a
series of future firmware updates for those models.
EOS-1D X Mark III
- Canon Log 3 option
- Lower bit rate option for 5.5K RAW video recording
- Lower bit rate option for all the IPB video recording modes
EOS R5
- Canon Log 3 option
- Lower bit rate option for 8K RAW video recording
- Lower bit rate option for all the IPB video recording modes
- Adding 119.88 fps option for Full HD (1080p) recording
These updates will be available free of charge from the Canon Europe support website in the future. Firmware updates for the
EOS R6 are also currently in development, including the fixes found in EOS R5 version 1.1.0 firmware.
