As already rumored before, Canon may release a new firmware for EOS R5 (B&H/Adorama/Amazon) in next few months. One of the new features is Cinema RAW light option to 8K recording. Now according to Apple, it seems that 8K Cinema RAW Light coming to EOS R5 has been confirmed.
From Apple:
This release also introduces significant performance improvements with new Metal-enabled plug-ins for RED RAW and Canon Cinema RAW Light. Transcoding 8K RED RAW video to ProRes 422 is up to two times faster on Mac Pro, and up to three times faster on MacBook Pro. And for the first time, Final Cut Pro editors can play and edit 8K Canon Cinema RAW Light.
