Shedding some light on CFexpress firmware and camera compatibility
- Thread starter Canon Rumors Guy
- Start date
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.

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.

NAND flash on its own is a really awkward and finicky thing to use. It takes a pretty intelligent storage controller with a lot of software tricks to turn NAND it something actually usable by a computer.

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.

Last I checked you needed the Angelbird card reader as well to perform a firmware update, so not that easy if you have another card reader.

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

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?
