CFexpress is the hottest memory card format of the moment and looks set to become the format of choice for cameras for professionals requiring the fastest possible data transfer speeds to keep up with the demands of ultra-high resolution image sensors and high bitrate 4K and 8K video.

At present only a few stills cameras support CFexpress out of the box, most notably the Canon EOS-1D X Mark III, but this could soon change. With CFexpress cards sharing the same physical form factor as the existing XQD card format, it's possible for older XQD cameras such as the Nikon D850, Z 6 and Z 7 to be firmware-updated to support CFexpress cards. This not only opens up possibilities for compatibility with newer, faster cards, it could also save you money. As any Z 6 or Z 7 owner will know, XQD cards are far from cheap, mainly because Sony has a stranglehold on the market. CFexpress on the other hand is an open-source standard and the usual big names in the memory card business are queuing up to offer CFexpress cards.
