I just picked this camera up on the board here and I just shot my first figure skating event tonight. Craw to slot 1, jpeg to slot 2.
Some of the jpegs look like this. Also, after downloading raw photos from slot 1, I can’t format the cf express card. The raw photo’s off that card seem ok. The moire is coming from my phone. All jpegs are not like this. Firmware 1.0.1
Any ideas? I never had this problem with my R5 or my R3 and used these exact cards.
Try a different card reader with the SD card. Most of the time when I've seen this, it was resolved by switching card readers, but it could also still be image corruption on the card.
