I’m starting to get annoyed as this is happening about every 2 of 3 days I shoot. The solution is to turn the GFX100S off, remove the card, then reinsert it. But today I had to do that 3 times in a row.
The card in question is a Sony TOUGH card, one that has been bulletproof in Sony cameras and others. I think it is a Fujifilm problem as the card has shown zero issues in any other camera.
I have not experimented with Slot 1 vs Slot 2, but I might do that, and also swap cards between cameras and see.
UPDATE: I swapped my 2nd Sony TOUGH card into the Fujifilm GFX100S. No issues since then. And no issues with the 1st Sony TOUGH card in the Sony A7R IV. I just don’t believe it is a card issue.
Note that buying some other brand card and seeing it work is an error in logic unless also testing another Sony TOUGH card (and even then, it remains statistically invalid). Sometimes little things like dirty contacts could explain. Or random camera bugs. What I know frm experience is that all my SanDisk cards have literally started falling apart (two halves cracking and wanting to separate) and that the Sony TOUGH cards are like little solid metal plates—vastly superior in build quality—I’m sticking with Sony,
