According to Canonrumors, Canon EOS R3’s bug for firmware v1.4.0 has been corrected and the new one is v1.4.1. You can update your firmware below the following instructions:
- Adds support for Speedlite EL-5.*
*The automatic light intensity adjustment of the AF-assist beam is not supported. - Adds [Register people priority] to the camera menu.
Pre-registered people can now be detected and tracked with priority.**
** This feature may not operate if faces are too small to detect, in profile or turned at an angle or partially hidden; for scenes where the subject is moving; or due to certain shooting environments. - Adds [Save/load comm. settings on card] to the camera menu.
Network settings can now be transferred between cameras of the same model. - Adds [Panning Assist] to the camera menu. When a compatible lens is used for panning shots, image stabilization and subject blur correction are applied during the exposure.
- Improves the Auto White Balance (AWB) setting to reduce the time it takes for the AWB result to be reflected in the camera’s viewfinder’s display when looking through the viewfinder.
- Adds Protect Images During [FTP Transfer] to the camera menu. Images transferred via FTP can now be automatically protected. The user can determine if images have already been transferred via FTP.
- Fixes an issue in which Error 70 may occur when using the camera with certain EF lenses after having updated the camera firmware to Version 1.4.0.
- Fixes an issue in which the original tracking performance of Servo AF cannot be attained depending on shooting conditions when performing high-speed continuous shooting using the electronic shutter after having updated the camera firmware to Version 1.4.0.
- Fixes minor issues.
