17th July 2025
Firmware Version 1.1.0 incorporates the following fixes and enhancements:

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 the ability to use up to 8TB of CFexpress cards.
Note
- Cards larger than 8TB require low-level formatting by the camera.
- Cards larger than 8TB are treated as 8TB cards.
- Cards larger than 2TB cannot be used for firmware updating.

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 already Version 1.1.0, it is not necessary to update the firmware.

The User Manual on our website has been updated accordingly. Please download the User Manual as well as the latest firmware. You can download it from the official website.

I got the notification from the Camera Connect app, and have used it to run the update. It seems to have gone smoothly. Camera restarts and requires you to enter a "password", but it seems more like a PIN, being numeric only. I'll report back after a play.

It's getting dark here, so unless there's a solar storm and clear skies this evening (seems unlikely), the camera will sleep a while.

I can report that the first time you fire up the camera after setting the password/PIN, it will require the PIN to be entered, but there is an option to turn it off.

The pre-capture tweak allows you to select anywhere up to 15 images to be recorded, but I'm not entirely clear as to how the selected frame rate affects the amount of *time* covered by the pre-capture. Will need to play - or find a Youtuber who's done it. ;-)

Seems only NZ as not up on UK page yet.

 

[Bucolic Old Sir Henry]

The original press release I saw at Canon Rumors says something like “globally on the 17th). It’s just that NZ always gets the new day first.

 

[David Berry]

Note the comment above the date in this screenshot from Canon Rumors:

"Update: Firmware has been pulled."​

​

A similar notice appears for the R1.

I wonder whether we are facing a repeat of FW 1.0.3 (released four months ago : 2025-03-18).

Vasko Obscura:

Why You Should Avoid Firmware 1.0.3​

​

In this video, I break down a critical issue with the Canon EOS R5 Mark II and explain why you should skip firmware version 1.0.3 — it’s been causing serious autofocus problems that could impact your shoots. The R5 Mark II is a professional workhorse, and for many creators and business owners, it’s a key part of their income. That's why it's so important to know about this firmware issue before it affects your workflow. Let’s hope Canon addresses this bug quickly — but in the meantime, stay on an earlier version if you rely on reliable autofocus.​

pulled already

 

[jcass]

Pulled already, but release notes said that they added a photo count to the Precapture config. Yay!

 

[Bucolic Old Sir Henry]

Canon Rumors says that it was pulled because of a card-related issue when shooting video. I don't shoot video - or not often, at least - so it remains to be seen if it has any other problems. I'll report back if I encounter anything...

 

[TwoWheeler]

Software most likely written by the same folks who wrote Canon Professional Print and Layout Manager...the very software that I spent much time spewing profanity at last night.

For some reason, it decided to stop recognizing my printer....my CANON printer...the same printer that every other piece of software I own had no trouble finding....

 

[MrSparks999]

Would appear the update is now advertised on the Canon UK site, but shows error when clicking the download button.

 

[David Berry]

Duade Paton tests firmware 1.1.0…

The major difference appears to be the introduction of PIN protection when switching on the camera. I'll avoid updating until I know with 100% certainty that that feature can be turned off! My main reason is that I turn the camera off — to automatically screen the sensor from dust — when changing lenses.

There is another ‘improvement’: the number of pre-continuous exposures can be reduced. Of course, I want more!

It can be shut off in the password managers tab.

Wrench menu there is a selection Manage password (Pword) can be toggled On or Off, it can disable. Additionally you Change password" and "Clear entered information".

Thanks Newton

The major difference appears to be the introduction of PIN protection when switching on the camera. I'll avoid updating until I know with 100% certainty that that feature can be turned off!

The first time you turn the camera on after installing the firmware you are prompted to create a PIN. The second time you start up you get the PIN entry screen, ands an option to turn the password off. Which I did...

 

[David Berry]

There is a problem relating the "Don't ask again" message.

The "Don't ask again" message must be pressed twice — once to highlight the box, then again to display a tick — before it will allow the R5m2 to be powered on without demanding entering a PIN every time.

 

[jcass]

Is there another screen that has to be disabled so that the password prompt does not appear at power-on?

 

[MrSparks999]

Hopefully you guys will find all answers to these questions before the rest of us get our hands on it

 

[Bucolic Old Sir Henry]

No PIN problem here. I did notice the AF seemed a bit sticky on the wrong thing, so that issue doesn’t seem to have been fixed.

 

[MrSparks999]

Heads Up, the 1.1.1 release is now available on the Canon UK site.

 

[MrSparks999]

Update downloaded, installed, PIN set up and then turned off with no issues.

 

[THXGEEK]

Update downloaded, installed, PIN set up and then turned off with no issues.

Confirmed. Same here.

 

[Photofarmer]

So a month on haven’t updated R5/6 but will over weekend no issues from guys that have updated.
Smooth sailing?
Cheers

 

[RedCobra]

Seems to me that the AF is a bit stickier in FW 1.1.1 than it was in FW 1.0.2. I skipped 1.0.3

 

[Photofarmer]

Password non issue ? not even annoying?

 

[jcass]

I saved my password in my password manager, just to be sure. Other than that, non issue, not even annoying. I set the password and set the option to never ask again. Haven't seen it since.
