Canon has released firmware v1.5.1 for the Canon EOS R3. It’s a relatively small firmware update that addresses named and unnamed bugs. Other cameras have also been updated, including the EOS R5 and EOS 1DX MK3.

Camera Remote Application: It is now possible to register the focus position in the preset function of the CR-A100. When used with the CR-S700R robotic camera system, it makes it easier for the photographer to focus on the intended subject distance and shoot.

It is now possible to erase only voice memos attached to images. In addition, it is now possible to add and add voice memos to protected images.

Enhanced security when sending captured images via FTPS transfer.

If you press the “Exposure Compensation/Aperture Value Setting Button” while looking through the viewfinder, you can check the time in the viewfinder.
