CFExpress is totally different from CF. It shares the same format as XQD cards but at 4-5 times the write speeds. XQD is used in D4, D4s, D5, D500, D850, Z6, Z7, and almost all upcoming pro and semi pro format cameras from Nikon. Will require a firmware update to work in those cameras which Nikon has promised will be coming in November.
I understand now. Thank you so much. Somewhere in the future I would like an 850 so I will watch for your future comments on how they work.
