Backup mode. What a silly idea to put two card slots in the camera but you can't backup unless you're willing to sacrifice speed. i know Fujifilm isn't the only company that does it but it's a poor design choice.I was hoping it would zip to the CF Express and then copy over at a slightly slower rate to the SD Card. But thanks for the reply. It's good to know.

So does the CF Express take the initial data from the camera and then later on the SD card catches up? I've been using CF Express only but it's a pain in the butt to use a card reader all the time. I'd rather just use a secondary SD card for compatibility issues, but would my buffer rate be effected?
