As promised Canon has released a major new firmware update for videographers that use the Canon EOS R5. This update adds external 8K ATOMOS Ninja V+ support via the HDMI port.

Firmware v1.4.0 also adds simultaneous movie recording to both memory card slots and the VPG 400 profile.

Firmware Version 1.4.0 incorporates the following fixes and enhancements:

  1. Adds support for outputting 8K/30p/10-bit video signals for ProRes RAW recording to ATOMOS's Ninja V+ recorder* via HDMI.
    * If you have any questions about ATOMOS products, please contact ATOMOS directly.
    * Please note that the recorder may become hot.
  2. Adds support for movie recording when the camera is connected to the CN-E18-80mm T4.4 L IS KAS S or CN-E70-200mm T4.4 L IS KAS S EF cinema lenses.
    * Still photography shooting is possible however performance is not guaranteed.
    * Movie shooting in vertical position is possible however performance is not guaranteed.
    * External power supply is required for AF operation during servo zoom operation. When there is no external power supply, AF operation is activated only when the servo zoom is not in use.
  3. Adds simultaneous movie recording capability on card 1 and card 2, however RAW movies and RAW(Light) movies cannot be recorded simultaneously on card 1 and card 2.
  4. Adds support for the VPG 400 (Video Performance Guarantee Profile), a standard based on the CFexpress 2.0 specification.
  5. Improves operation stability when using the RF 400mm f/2.8L IS USM and RF 600mm f/4L IS USM.
  6. Fixes an issue in which, during HDMI connection, if the camera's screen turns off, a zebra pattern is displayed via the HDMI output.
  7. Fixes an issue in which sufficient image stabilization effects may not be attained immediately after the start of shooting.

  1. Loving the supply of firmware updates. They could always have something more, and hey, having bought an R6 for what it is and understanding the limited supply of firmware on previous cameras leaves me feeling an uneasy FOMO feeling like never before - very clever Canon marketing!
  2. This is amazing, I can now set the shutter burst rate between not quite fast enough to way too fast.

    Hang on, no I can't.
    Canon doesn't want you to do fast burst too often, that's why they give you no other choice. You'll have to buy the R3 for choices.
  3. Too bad this update does not provide in essence any update for still photographers:-(
    Not a new feature but IBIS fix is an update for still photographers. I do not shoot video but this fix alone is reason enough for me to upgrade the firmware.
  4. Although I am rather happy with my R5 I can think of some issues regarding stills photography:

    They have to fix the loss of manual focus setting when shooting timelapses. (there has been an issue reported by a member doing astrophotography). That's a bug!

    They could give us the setting where we chose between release and focus priority in servo mode. R5 is maybe the only camera that does not have it!!!
