Netflix has rejected the Canon EOS R5C for production certification, and we're told that Canon doesn't have any intention to address the issue like Sony did with the FX3.
Neither Netflix or Canon has spoken directly on why the camera was denied, but the only thing we and others can think of is that the camera lacks Canon Log-2. There may be some other image quality reason that we don't know about. The Canon EOS R5C seems to have every other feature required by Netflix for certification.
The Canon EOS R5 C can still be used for productions, but footage from the camera cannot make up more than 10% of the total runtime of the production.
We'd love to hear more on this topic.
