Hey everyone,
Today, I updated the firmware on my R5 Mark II to the newest version eosr52-v1.1.1 and downloaded the latest Manual version. As always it was a piece of cake. I turned off the "Security Option" and all is set up to my likening. This new v.1.1.1 firmware update is loaded with "Fixes", "Addon Functions", and "Improvements" as follows, (Copied from Canon's Firmware File Description):
This firmware (Version 1.1.1) includes fixes for the following issues identified in Version 1.1.0: 1. Fixes an issue where video could not be recorded correctly when using a memory card larger than 2TB with the [Pre-recording] setting enabled. This firmware also incorporates the following changes introduced in Firmware Version 1.1.0: 1. Improves security features. A password must be set initially. •Adds the ability to review the history of any changes made to the password, network information, or other settings. *For more information, please refer to the 'Setting a Password' section in the Advanced User Guide on cam.start.canon. 2. Enables firmware updates to be performed when the camera is connected to the internet and new firmware is made available on Canon servers. 3. Adds the ability to automatically detect Flicker at 100 or 120 Hz during Live View display. 4. Adds the ability to register focus position as a presets on the CR-A100 Camera Remote Application. This ability makes it easier to focus on subjects at the intended distance when the application is used with Robotic Camera System CR-S700R. 5. Adds the ability to select [Case Special] to expand Servo AF characteristics which is effective for subjects located behind a net in sporting events, such as badminton or volleyball. 6. Adds support for the Software Development Assistance Kit (EDSDK/CCAPI). 7. Adds a function that simultaneously protects images when they are rated. 8. Improves image stabilization control for lenses compatible with Peripheral Coordinated Control. 9. Adds support for the Software Development Assistance Kit (EDSDK/CCAPI). 10. Adds to lower the image capture frame rate to help prevent overheating when connected to CR-A100 in extended remote shooting. 11. When transferring images with voice memos via FTP, the transfer order priority has now changed with voice memo (Wav) file being sent first followed by image file. If a voice memo is added to an image queued for transfer, the image and voice memo are now sent last. 12. Adds the ability to set the number of shots captured in pre-continuous shooting mode. 13. Adds the ability to set [Airplane mode] to shooting button customization. 14. Adds the ability to enable [Exposure Simulation] when a flash unit is attached. 15. Improved AF tracking during video capture for subjects that are difficult to focus on. 16. Fixes an issue in which Err70 may occur when enlarging an image after shooting with [Blackout-Free Display] set to "On" and [Servo 1st image priority/One-Shot AF release priority] set to "Release priority". 17. Fixes an issue in which Err70 may occur during Bluetooth communication due to interference from other Bluetooth devices. 18. Fixes an issue in which Err70 may occur when repeatedly shooting in the "High-speed continuous shooting +" mode. 19. Fixes an issue in which Err70 may occur immediately after startup when shooting with the electronic shutter. 20. Fixes an issue in which Err70 may occur during video recording in "FHD239.8P/200.0P". 21. Fixes an issue in which Error 70 may occur while filming in video mode with frame rate set to "50.00P" and [Movie Digital IS] set to "On" or "Enhanced". 22. Fixes an issue in which Err70 may occur during shooting when both [Pre-recording] and [Auto send] to image.canon are set to "Enable". 23. Fixes an issue in which the camera may stop functioning properly when [Image Review] is set to "Off" and the monitor entered low brightness mode after pre-continuous shooting. 24. Fixes an issue in which video recording may not be possible when using Remote Live View shooting in EOS Utility while outputting via HDMI. 25. Fixes an issue in which large RAW image files may not be transferred via Camera Connect. 26. Fixes an issue in which a horizontal line may appear momentarily in the viewfinder. 27. Fixes an issue in which the camera may not connect to Wi-Fi 7-compatible routers. Contact a support representative regarding use of the Software Development Kit for digital cameras. If the camera's firmware is Version 1.0.1, please update the firmware with only one memory card inserted into the camera. If the camera's firmware is already Version 1.1.1, it is not necessary to update the firmware. Notes: Users manual in the WEB is updated accordingly. Please download the manual as well as the latest firmware. You can download it from the official WEB site.
If you own an R5 Mark II, and you haven't updated your firmware, then let this be a reminder to update your firmware to the lates version eosr52-v1.1.1 as it will fix many issues that you may be having.
