Yesterday I reported on compatibility points with the Canon EOS R5 working firmware v1.4.0 and Exascend CFexpress reminiscence playing cards.

After speaking to a couple folks, I’ve come to considerably of a conclusion that there’ll doubtless be some bumps alongside the best way on the subject of CFexpress firmware and digital camera firmware. Exascend shouldn’t be the primary firm that has had some compatibility points with the Canon EOS R5 and CFexpress playing cards.

I spoke with “Tig” from Camnostic this morning in regards to the points which have provide you with CFexpress and compatibility. Remember to test that website out for nice info on CFexpress playing cards and extra.

What it seems to boil all the way down to is that CFexpress is a comparatively new customary, and there are going to be some conflicts with reminiscence card producers’ and digital camera producers’ interpretation of the usual. I do know of points which have arisen with different producers as effectively.


Angelbird, an excellent producer of CFexpress playing cards had a problem with the EOS R5 some time in the past that delayed the digital camera 4 seconds on startup earlier than the cardboard was initialized. This concern was corrected by a firmware replace device from Angelbird that anybody may obtain and use. It’s my understanding that Angelbird constructed within the skill for the sort of replace of their firmware. Angelbird and Canon additionally labored collectively to get the difficulty corrected as Angelbird launched these reminiscence playing cards previous to the supply of the Canon EOS R5.


Delkin had a problem as effectively, however customers needed to ship their reminiscence playing cards again to them to get the wanted replace for compatibility.


Now to Exascend and the difficulty that I reported yesterday, I’ve been advised that Canon and Exascend applied the CFexpress customary a bit in another way when it got here to VPG400 inflicting the difficulty.

We began investigating studies that Canon’s newest firmware for the EOS R5 might trigger points with our Important sequence of CFexpress playing cards final week. Our engineering crew shortly found that Canon EOS R5’s 1.4.0 firmware adjustments the best way CFexpress playing cards are handled by the digital camera system.

With the most recent EOS R5’s 1.4.0 firmware, our Important CFexpress playing cards enter a unique working mode than in earlier variations of Canon’s firmware. This causes a compatibility concern based mostly on completely different interpretations of the VPG400 specification and is unrelated to card efficiency.

To help this new working mode, a CFexpress card firmware improve is required.

As of earlier this week, we’ve already made the mandatory adjustments to help Canon EOS R5 with firmware model 1.4.0 (and above) in our newest CFexpress firmware, that means that every one our new CFexpress playing cards are suitable with the brand new 1.4.0 firmware. Nevertheless, as a result of approach that CFexpress card firmware upgrades work, we have to manually replace the firmware for Canon EOS R5 customers with Exascend Important CFexpress playing cards bought earlier than we began pushing this improve to new playing cards.

How is Exascend fixing this concern for purchasers?

Product high quality and buyer satisfaction are the cornerstones of our enterprise. Subsequently, we are going to ship model new substitute CFexpress playing cards upgraded to the most recent firmware to any person with legitimate proof of buy. This ensures that our clients can proceed utilizing their Canon EOS R5 system with Exascend storage as quickly as attainable.

We additionally don’t need clients’ unique playing cards to go to waste, so clients can even ship their unique playing cards to us for a free firmware improve. To make clear, that signifies that clients who return their unique playing cards to us will quickly have an additional Exascend CFexpress card to spare along with their new substitute card.

We need to apologize once more to all our card customers who have been impacted by points with the Canon EOS R5 firmware replace, and going ahead, we are going to work extra carefully with digital camera distributors to make sure future card compatibility.

You learn that proper, Exascend gives you two equal playing cards on your troubles. A brand new card is shipped out ASAP so you will get again to capturing. You’ll then ship in your incompatible card to Exascend and they’ll replace the firmware on the cardboard and ship it again to you.

This stage of customer support is nice in my view.

Now to Canon

I realized about this concern on the Canon Rumors Discord from an EOS R5 person that up to date to firmware v.1.4.0 and hit the snag. Fortunately he didn’t have an essential shoot to do this day, as this might have value him more cash to get a brand new card, or he would have needed to journey with SD playing cards, which isn’t perfect in some conditions.

Why can’t we roll again firmware one model when these points come up? Is there a technical motive? Is there a perception that everybody must be working the most recent firmware? This actually wouldn’t be the case, as numerous folks will keep on with firmware that works for them.

There are all the time going to be bumps within the highway on the subject of new requirements and merchandise, firms are racing to fulfill deadlines and get their merchandise to market. That is simply the character of many expertise companies.

Thanks once more to Exascend for clarifying issues for me, and I apologize for leaping to an ignorant conclusion.

We will be happy to hear your thoughts
