Fujifilm details support for CFexpress, SD and SSD media with GFX100 II
Fujifilm has published a list of recording media which is compatible with the new GFX100 II (and X-H2) and it’s an extensive resource. It can be found on their website.
Unsurprisingly, it correlates with other camera marques’ recommendations for CFexpress cards and SDXC cards with a high minimum sustained write speed, for cameras like the Nikon Z8/9 and Canon EOS R5. You can read more about my thoughts on the matter, here.
