Caution: Sandisk SD Card Issue with 5D Mark IV

[tron]

I got a Samsung PRO+ 64GB SDXC card. I have used it 2 days. Up to now I have not encountered any issues. I know it is too early just wishing to update. Anyway right now I have rather a sufficient set of cards so I will not get any more (until that 5DsRMkII at least ;D )

UPDATE: Received my new card and initiated a test read/write with my 5D4 with no issue.

Long term issues though, jury's still out.

What do you mean by long term issues? Are you not sure how it will perform over the long term? Or are you experiencing something that makes you believe there will be an issue long term?

My older Sandisk 64GB SD cards seem to be fine. Just updated the firmware, so maybe it'll help.

I believe my incident with non v30 sandisk was one off and that's it. Up to now I have taken hundreds of photos with no issues (at least with my new Samsung card). When it fills I will start alternating my other sandisk sd cards to test them.

Well, if I recall, a couple folks up thread complained of occasional camera lockup when using these cards...

The card appears to function completely normally so far though. Definitely not experiencing what the OP did, that's for sure.

Just wanted to add, I had the same problem with this card:

I currently have a 5DMKIV on 1.0.2

Card is authentic. Used the card previously in my MK3, 6D, + 7DMK2 with no issues.

Can you please clarify what problem(s) you are having exactly? There seems to be two different issues at the moment - one being completely non-functional (unable to format/reformat the card in 5D4) and the other that causes issues when using (able to format/reformat the card in 5D4).

I took a few images and turned off the camera. When I looked down it was froze on "writing images to card". Then a "Card 2 cannot be accessed" error. I popped out the battery and it fixed itself.

UPDATE II: After a couple hundred images shot to that new V30 card, downloaded and reformatted in-camera, no issues.

I know my sandisk extreme pro cards have never exhibited any issues with the other cameras. I have ordered a different sd card (samsung pro+ 64gb) to test if I will get any issue...

Cards are made in batches using memory and controllers made in batches. Its entirely possible to produce a marginal batch of cards. If a marginal card meets a camera that is using a faster clock speed, for example, then occasional glitches can happen. The fact that the card works on your other camera is no guarantee that it will work on a newer one that may push a card harder.

This type of issue can be very difficult to detect, because another batch may be a little faster and never have a issue. Not all cards of the same part number are the same, there is variance.

I know this is an old post and I'm new here..

I'm having this issue and wanted to see if an update fixed this for anyone please?

Be sure that your camera is at the latest firmware level. Canon did release a new firmware at one point that fixed some communication issues with the SD card. I'm not sure if this applies to this specific issue or not, but it's worth a try.

My "problematic" Sandisk card had similar issues with not only 5D4 but 200D as well. However it worked OK with previous models (5D3, 7D2). After a format in PC I put it in my G7XMkII and I formatted it there and It works OK there. So I did not throw it away

FYI, the 64GB Extreme Pro Sandisk SD card (95MB/sec) was OK with (my now returned for other reason) EOS 5D Mark IV.

Yes, I have 20+ 64GB SD cards (Sandisk Extreme & Extreme Pro) that all work fine with the 5D4.

It's good to know that I'm not the only one who can't seem to stop buying 64GB Extreme Pro's

This is definitely my favorite SD card.

I found something better than that: The 128GB Sandisk Extreme Pro SD card ;D

I also use the 128 GB Extreme Pro SD card and love using it.
