The EOS R5 camera has a new firmware version available which primarily makes it work with the new battery pack, LP-E6P.
Firmware version 2.1.0 incorporates the following enhancements and fixes:
1. Enables functions to be used without limitation in conjunction with the new Battery Pack LP-E6P.
This makes it possible to shoot at the same continuous shooting speed as when using LP-E6NH.
In-camera charging of LP-E6P is also supported.
2. Adds [Protect Images] and [Rating] during FTP Transfer.
3. The following issues have been fixed.
3-1. Fixes an issue, in which when Wi-Fi is disconnected, Err 70 occurs.
3-2. Fixes an issue, in which when shooting subjects that are smaller in the frame, the card access indicator blinks and operations can no longer be performed.
3-3. Fixes an issue, in which when performing shooting in high-speed continuous shooting + mode with the [Highlight Tone Priority] option set to [ON], focus may not be achieved when certain ISO speed settings are used.
If the camera's firmware is already version 2.1.0, it is not necessary to update the firmware.
The firmware can be downloaded for free from Canon support, with information on how to install included in the download.
