Yesterday I reported on compatibility issues with the Canon EOS R5 running firmware v1.4.0 and Exascend CFexpress memory cards.
After talking to a few people, I have come to somewhat of a conclusion that there will likely be some bumps along the way when it comes to CFexpress firmware and camera firmware. Exascend is not the first company that has had some compatibility issues with the Canon EOS R5 and CFexpress cards.
I spoke with “Tig” from Camnostic this morning about the issues that have come up with CFexpress and compatibility. Be sure to check that site out for great information on CFexpress cards and more.
What it appears to boil down to is that CFexpress is a relatively new standard, and there are going...
If you want to get rid of this obsolete espresso machine, I'd be happy to scrap it and send you as a replacement a fully firmwareable Crappuccino GTS X200 proudly made of aromatic plastics in a highly qualified Asian sweatshop.
Yeah I can confirm I don't have issues with the Sony Tough either (256Gb).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.
That's impressive, but may imply they acknowledged their fault, that is, it's them who broke the protocol/compatibility, not Canon.Great post, Craig. Upgradeable firmware was one of the reasons I went with Angelbird. But I love the way Exascend is handling the issue. Very impressive.
No, you need to read the statement carefully: "different interpretation of the standard". All standards leave some leeway for interpretation. That's why you have Bluetooth UnPlugFests for testing (real world) compatibility, UNH testing of Ethernet hubs, nics and switches, and so forth.That's impressive, but may imply they acknowledged their fault, that is, it's them who broke the protocol/compatibility, not Canon.
I think being able complete multiple formats in Camera using the cards I noted in my previous message proves LOADS of things first and foremost it shows that the issue reported on the Exascend cards does not occur on MY two 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."Yeah I can confirm I don't have issues with the Sony Tough either (256Gb).
However note that multiple formats in camera don't prove anything, continuous shooting or video recording do.
Not the best sort for me - I prefer companies that are competent enough to get it right before I buy. But, better than washing their hands of it, which would be suicidal in such cases.Yes a reputational Minus turned into a definite Plus. Thats the sort of company I will buy from.
I recently used the Canon R6 firmware 1.4.0 and the fast Kingston Canvas React plus 300MB / s v90 II U3 SD cards and there was a problem. The camera did not react for about 5 seconds during recording and switching off. Only then did some of the information displayed in the viewfinder appear. Only after that was it possible to continue recording. In a situation where you need to take quick shots and you can't wait and it irritates you. It is a pity that in Canon there is no red frame next to the image as it is recorded. Here, under stress, I couldn't even see when the recording started and when it didn't.
Lexar is a lower-end brand nowadays. It's owned by Longsys, which is on a Commerce Department watch list. This means that there is a hassle if you need a card replaced, as they are not allowed to directly send a card for replacement. I know that seems to make no sense: that you can purchase a card through a third party, but they can't service it. I actually contacted Commerce to ask some questions a year ago, and never heard back under the old administration. Might try asking the same questions under the new administration. Not holding my breath on a response.
Sony Cfexpress Tough or Lexar, leave the rest alone, is $30 bucks that important?
As someone that has always preferred to carry more smaller capacity cards than one big card Sony's claims of equal performance was why I went with 3 of this 128GB cards after experiencing issues with the ProGrade Gold 128GB (I should have read the specs more carefully as this card could not record 8K Raw).(lower capacity cards use less capable hardware, which means they're slower)
