It came to my attention today that there appear to be compatibility issues with the latest Canon EOS R5 firmware and Exascend CFexpress memory cards.

Shooters with a Canon EOS R5 and firmware v1.4.0 are getting camera lockups when attempting to format the memory card in the Canon EOS R5.

From Exascend

Some Canon EOS R5 users have reported problems using their Exascend Essential CFexpress after updating their camera system to firmware version 1.4.0.

If you are experiencing similar problems, please contact the store or online retailer where you bought the product to proceed with a firmware upgrade of your Exascend Essential CFexpress card that ensures continued compatibility with the Canon EOS R5 system.

The solution offered by Exascend doesn’t appear all that helpful, I’m not sure how Amazon is going to help owners with a firmware update for the memory card.

I have reached out to Exascend for further clarification

I use Delkin CFE-B cards in my R5 without any problems, but I'm still on firmware 1.3.1.

I think it's advisable for all R5 users to stay on 1.3.1 until it becomes clear whether other card brands are affected by the latest update.

I was not aware that memory cards need firmware to run.
They do, since they are in essence tiny computers nowadays. But what we're talking about here is that the changes Canon made to use the new VG400 standard for CFexpress seems to have bad interactions with Exascend cards.

I have that card and I have the new firmware installed. I have had no problems with it, but that is for the 128GB version. Not sure if any other storage sizes make a difference.

For those holding off on upgrading to 1.4.0 on the R5. I can confirm no issues with Sony Tough 128GB CFe and ProGrade Gold 128GB CFe cards after multiple formats in camera.

This is likely a knock on bug from - "Adds support for the VPG 400 (Video Performance Guarantee Profile), a standard based on the CFexpress 2.0 specification." in 1.4.0.

I would not be surprised if Exascend missed something in the CFexpress 2.0 protocol that was not an issue until VPG 400 was enabled on the R5. I see this all the time with the Onvif protocol and manufacturers cutting corners.

This happened with my 256gb Transcend card after a previous update. Did a warranty swap on it. This is why I carry cards from different brands as backup.

The only problem I've had with the 1.4.0 firmware update is that it turns off eye detection on the R5. I didn't expect the update to turn off eye detection and it took me a minute to figure out what was going on. Eye detection seemed to partially work but after going through the menu, I realized that the update turned it off. I shot almost 1,000 shots last weekend with 1.4.0 and no problems that I can see. Once you get eye detection turned on, it seems to work better than the previous versions. This is just an antidotal opinion and not based on any actual tests.

To be fare eye detection being disabled has only been reported by @VegasCameraGuy at this point so this may not occur for most users.

From the 1.4.0 thread
Firmware 1.4.0 Problems. The update turns off Eye Detection and turns on touch display to take a picture. Go into AF and set the AF Method to Eye (1st selection) then Enable Eye Detection which the update turns off.

I had no issues when I updated and I loathe touch to activate shutter!!!!! So I would have noticed that PDQ:D

Not for me though. I updated yesterday and both are still set to my last settings.

No changes in the configuration for me, also. Both are still set to my last settings.

@VegasCameraGuy not doubting your personal findings just that you may have a customization\setting that at least 3 others (myself included) do not have that resulted in some strange things on your Camera and not ours.

Cheers

So far one person on DP review is getting some camera freezes with the new firmware he wasn’t getting before.

Does anyone have experience with Sandisk 512Gb CF express and this new firmware?

I have Prograde Cobalt 325 and Gold 256. No issues with both cards. Tried continuing recording on either card and they both work as advertised so far.
