Canon has released a new firmware update for the EOS R5 II, and says it's currently working on removing a limitation that shows up when using the new camera with an older LP-E6NH battery.

Firmware version 1.0.1, which should soon be available on Canon's site, is mostly about bug fixes and improvements. According to Canon, the update will:

• Fix an issue in which movies captured in RAW format may not play back properly on applications due to the attached lens and camera not communicating properly.
• Improve the stability of the touch operation control when the Touch Control is set to Sensitive.
• Fix an issue in which the camera LCD display may become abnormal after the camera resumes operations from the viewfinder off state.
• Fix an issue in which the camera may stop working properly when the shutter button is operated while the BUSY message is being displayed on the screen.
• Fix an issue in which Err70 may be displayed when the display mode is switched between the LCD screen and viewfinder while the BUSY message is being displayed on the screen.
• Fix an issue in which the camera LCD display may become abnormal after using EOS Utility to capture and import movies.
• Fix an issue in which movies captured using EOS Utility may not be played back on the camera.
• Optimize the auto white balance for specific environments when the Custom Picture function is set to ON.

The company also told DPReview that it'll release a firmware update 'later this year' to let the EOS R5 II record 23.98/24p video, even with an older LP-E6NH battery installed. There will still be limitations when using the LP-E6NH battery instead of the LP-E6P that comes with the camera; according to Canon's manual, using the older battery will disable:

• Recording in 8K DCI/8K UHD/RAW/SRAW, Fine image quality, and 239.76/200.00/119.88/100.00/59.94/50.00 fps frame rates

• HDMI RAW output

• Still photo shooting during movie recording

• High Frame Rate movies

• Pre-continuous shooting

• Using Wi-Fi / Ethernet

While the 24p frame rates aren't officially included on the no-go list, Petapixel has reported that people weren't able to use them with the LP-E6NH battery installed and confirmed the omission with its own tests.

Canon says it hasn't finalized when the update enabling 24p will be available, but we'll be sure to update you as soon as it's available.
