To day I was shooting on the field with 5D4 raws in CF and Jpegs in SD. All cards were Sandisk Extreme Pro.
CF was the 64GB 150/160 MB/sec Udma 7 and SD was the NON V30: 64GB 95mb/sec U3
Taken from my Amazon order:
SanDisk Extreme PRO 64GB SDXC UHS-I/U3 Memory Card up to 95MB/s Read FFP (SDSDXPA-064G-FFP)
My camera froze with error 02 (if I recall correctly because I was in the middle of shooting so I was very frustrated). I waited for a few seconds and then switched to my 7D2 (anyway I was shooting birds so 7D2 was fine).
But this was my second 5D4. I had shot a few hundreds with my 1st 5D4 same cards, same Raw+jpeg split to 2 cards and I did not have a problem. So I kind of feel stupid. That camera's serial number started with 03. My current's 5D4 serial starts with 04 (in case someone is interested).
Now I have low level formatted the sd card and then formatted it once more (non low level). But this is BS. My other 2 5D3s and 7D2 never had a problem with these (same vendor & type) sd cards.
After a few of hours when I wanted to switch to my 5D4 again I changed it to use Compact Flash only. I did not experience any problem with CF only.
It's been frustrating, to say the least. CF seems to be the reliable card slot until this issue is addressed, but that is not what I purchased. I will pass along the additional information to the Canon people I have been in contact with about this case.
Couple of questions:
Was the Amazon order fulfilled by Amazon? Or was this an order of a card shipped and sold by Amazon as the seller?
You have two 5D4 bodies in your possession, correct? Are they able to READ each other's cards (shoot CF & SD in body 1, insert into body 2 to review and reverse)?
Have you looked at the firmware version on both cameras by any chance? I'd assume they would be the same, but maybe not? Any differences in the metadata between the two that you have noticed?
