Canon 5D mk iv - Err02

[PhotoSimon]

Curious as to how many 5D mkiv owners have had the Err02 fault where the camera can't write to the second card slot - The SD card. The camera locks up and usually has to have the battery pulled in order to restart. Usually resulting in a few lost images . . . one wedding photographer I know lost his first kiss shot!

I'm a member of quite a few Facebook groups and I'm seeing this issue reported more and more on the mkiv. I've not had it on my camera yet but a few close friends have now seen this on a number of occasions. One guy I know has confirmed that he still gets it with the latest firmware 1.0.3 and whilst using the UHS-1 class 3 SanDisk Extreme SD cards (these are the same ones I use).

I'd be interested if you've had the fault if you could give as much detail as possible about when it occurred . . . i.e. lens type, memory card details, shooting mode, camera configuration. We've not spotted any pattern yet and are not sure what triggers it. We've reported this to Canon and they are referring the issue to a product specialist who is going to call back in a few days.

Its likely a timing issue. Canon times the various parameters of saving to a card according to established specifications with a safety margin. However, some cards may not quite meet the specification, and sometimes fail to write if they are on the borderline. I'd stop using any of the similar cards and get some new ones of a different model. There are so many card types and lot to lot variations that its impossible to test them all, and using even slower timings to accommodate a possible out of spec card slows it down for everyone.

I got it once only. Since then I got a new sd card and I haven't encountered it again but recently I stopped recording on both cards. A few days ago I just copied in camera the shots in CF card to the SD card.

But the SD card in error had been tested more or less so I think I will revert back to the previous sd card to check it again (that sd card had worked a lot in my 7D2 with no issues).

The specific card was sandisk extreme pro 64gb 95mb/sec uhs-i.

Any new info on this issue? I've had this error twice now on my 5D MkIV. The last time was using a Toshiba 128GB micro SD card with an SD card adapter, and a Sigma 24mm art lens.

Actually, both times it was with that card. The other time, I think I had the 50mm Sigma art on it.

There are so many counterfeit Toshiba cards out there, that would be my first thought. $10.99 for 4 of them - Really

Fair enough, but I have a hard time blaming the same card that has always worked flawlessly in my MkIII. :

Did not spend three grand on upgrading to a new camera for it to be less good than my old one.

I didn't spend three grand upgrading my camera to use the cheapest, sketchiest microSD card I could find.

Get a card that isn't garbage.

 

[Kit Lens Jockey]

Well then what type of card isn't "garbage?" Is Toshiba not a name brand electronics manufacturer?

I had a one off issue with a Sandisk SD Extreme Pro card (bought from Amazon prime) which worked fine with my 7D2 and 5D3 for months if not a year. No issues at all. It froze my 5D4 with the same error. Obviously a 5D4's issue but fortunately it was a one time error (up to now).

I've had my MkIV since mid October 2016, I use the SanDisk Extreme Pro SD and CF cards I used in my 6D. I've never got an error message, still running firmware 1.0.2.

 

[LonelyBoy]

The fact that the two above posters use the same card and one got the error and one hasn't is... troubling. Would be easier if it were certain cards, even if they should work.

The 5D MK IV likely has faster clock speeds than older cameras, so its entirely possible that a card might work fine on cameras with slower clock speeds but fail at faster speeds. My 5D MK III did not support UHS-1 which means it had the slower clock speed.

The timing issue rears its head again, a card that worked at slow clock speeds but not at faster ones.



Scroll down to the chart showing bus speeds, each generation of SD cards gets faster bus speeds, so a newer camera not working with a card which did work on a older model that used slower memory bus speeds is a possible, even likely reason.

https://en.wikipedia.org/wiki/Secure_Digital

The non UHS-1 5D MK III used 25 MB/sec bus speeds, a UHS-1 will use 50 or 104, a UHS-II will use 156 or 312, and UHS-III will use 312 or 624.

Thanks for the useful info, in contrast to simply berating my SD card choice as garbage. So, how about this SD card? Should that work well? I have never heard of the brand, but perhaps I am just new to the world of high quality memory cards.

Transcend has lots of users who swear by them. I have one card that came with a camera, and it worked fine. The main issue is to buy cards from a known source. DO NOT BUY FROM AMAZON. Why, you ask? It's because Amazon uses a process they call Inventory Co-Mingling where they pool inventory from many sellers. This means, in a nutshell, that you do not know what or where the card you are getting came from. You see a sold by Amazon tag, but the inventory may have been supplied by someone else who sent in counterfeits.


Its a optional feature, I sell on Amazon Prime and turn Co-Mingling off. https://www.wsj.com/articles/on-amazon-pooled-merchandise-opens-door-to-knockoffs-1399852852

Toshiba is the only card that I have experienced issues with, one card bricked two dslrs several years back. A person bought my almost new 30D when her camera died. It was working fine and then she put her Toshiba card in it, and that fried the power board. Then she realized it was the same exact process when her old camera died. Canon repaired the 30D under the Warranty, my camera dealer sent it to them.

 

[Kit Lens Jockey]

Yeah, I know Amazon's inventory sources are largely unknown. Looks like B&H's prices are pretty comparable anyway.

I'm contemplating just buying a large capacity CF card as their prices aren't all that much higher than SD cards, and this error thing is really bothering me.

Are Sandisk CF cards generally regarded as being decent?

Hi, this was the first issue I encountered on my new 7dmkii, serial no. starting 02, happened two or three times and was overcome by removing the battery, I thought it was the memory card so had it exchanged back at the store for a new one and it was okay for a while before the error surfaced again, I should say it only seemed to happen with the CF card, SD never gave a problem, time passed without too much of a problem then I found the camera completely freezing occasionally, remedied by battery removal, the final straw came when I couldn't review images just after taking them.
I have no local camera store so I had purchased the camera through an electrical store and thankfully took out an extended warranty with them, part of which was a three week repair promise or a replacement to be issued.
On the eve of the end of the third week I contacted the store to see if the camera was due back from the canon repair shop but they couldn't give me an answer but to contact them the next day, I was in the store the next morning and with still no prospect of my camera back invoked the replacement through the warranty.
I had a few days to wait for the replacement to arrive and surprise, surprise, my own camera appeared in store the same day but it was a no brainer to have the new camera leaving them with my old one. curious as to the repair needed on the old one I found out that a PCB had been replaced, unfortunately no precise details to which one and I would never find out if the fault had indeed been removed, I have been happily using my new camera for a while now with no repeat error.
So although undoubtedly memory cards do have reliability issues my experience was with the camera.
AS a new "poster" can I thank the wider Rumours community for having taught me quite a lot in the time I have been monitoring the site, I marvel at times the quality of the images displayed and wonder what it is I'm not seeing that the professional's do.

Mine was running 1.0.2 when it had the error. I have upgraded to 1.0.3 but I have also changed card. Still, I formatted the card on my laptop, then low level formatted on camera and then formatted again! Not saying that these formats resolved everything necessarily but they certainly didn't hurt...

Changes in the Firmware
Firmware Version 1.0.4 incorporates the following fixes and improvements:

1. Fixes a phenomenon in which a red-colored area may appear at the bottom-center of a captured image when shooting in bulb mode or during a long exposure.
2. Fixes a phenomenon in which the autofocus may not respond when the autofocus is initiated via pressing the shutter button, the AF-ON button or the AE lock button when configured in the custom control menu.
3. Enhances the reliability of communications between the camera and SD card.
4. Fixes incorrect wording on the Finnish language menu screen.


Ok, so can we admit that maybe Canon messed up the SD card communications, and it's not that my SD cards aren't up to the lofty professional demands of the 5D MarkIV?

I just ran into this issue this past weekend. It was in the middle of taking several sets of 5-exposure bracketed shots. The camera just kind of locked up and became unresponsive. I was able to resume shooting after waiting a few minutes. Since then, whenever I turn on the camera with the CF card in, the red light on the camera flashes constantly as if it is busy processing something.
