According to a report on Canon Rumors, Canon is going to be releasing some firmware updates for the Canon EOS R5 mirrorless camera. It’s not really much of a surprise, as most manufacturers seem to release cameras before they’re ready these days, following them up by a flood of firmware updates shortly after they start shipping.

But one of these future updates seems to specifically address some of the “overheating” issues to extend the record time limits – which would, again, suggest that the overheat limitations may be hard-coded into the firmware and have nothing to do with the actual temperature of any part of the camera.

CR says their source tells them that these updates will come to the EOS R5, although they may not all come at the same time in a single firmware update. They may come in several releases over time. There’s also no mention of when we might be able to expect them aside from “soon”.

  • Addition of Cinema RAW light option to 8K recording
  • Addition of CLog 3
  • Increased record time limits (but don’t expect a huge boost)
  • Various bug fixes

The addition of Cinema RAW light might help to reduce the heat build-up in the camera if the files it has to write out for this format aren’t quite as heavy as those it currently creates for 8K RAW. As to what they may do to increase the time limits and reduce recovery time of other resolutions and formats is unknown. It may be as simple as just setting a new value in a timer somewhere, or they may actually be able to increase efficiency to reduce heat generation.

Only time will tell. We may, as CR mentions, see other changes come to the EOS R5 as well (and I think it’s likely), but the ones above are apparently the ones taking top priority and will be coming first. Again, though, it may be over several firmware updates and not all at once.

    RAW light would increase heat because of compression.

      Agree. And as the camera have such long cooling time that it will limit it’ real usage in video; Raw Light or not.

      In another hand, overheating seems to be a complete fabricated excuses with a timer that override the temperature reading.
      Even under low temperature or without recording, the overheat is reached. The temperature displayed in the EXIF data being completely acceptable, and LIDR camera reading showing also a almost cool body.

    The limits built into the firmware based on timing and not based on temperature are probably to prevent the entire camera self-destructing if the temperature sensor is faulty. I wouldn’t expect them to change this.

      If the temperature sensor (assuming it even has one) is faulty, then I’d want to know and have the system repaired. I wouldn’t want to be limited to Arizona desert time limits if I’m shooting in the Arctic :)

      I tried to find the proper respectful words to say about your comment, but I couldn’t, so I’ll keep my mouth shut.

    If this turns out to be a limitation put in by Canon then think about what the camera will be able to do once they remove those restrictions. If it’s not actually overheating and is just being crippled then this firmware update could be the answer to Canons unhappy R5 and R6 buyers. I have not had my chance to try one out for myself but based on those who have it sounds like it will be a promising camera with this update.
