Last week the CompactFlash Association announced new CFexpress 2.0 specification with up to 4000MB/s maximum theoretical performance. We now also have six companies that will produce CFexpress memory cards:
Nikon will release firmware updates with CFexpress compatibility for the following cameras: Z6, Z7, D5, D850 and D500.
The new Panasonic S1 and S1R mirrorless cameras will also support CFexpress.
