The Nikon Z6 is a 24.4 megapixel full-frame mirrorless camera that features a single memory card slot. The single slot supports CFexpress Type B cards and XQD cards.
The CFexpress 2.0 standard is supported but not the latest 4.0 standard. CFexpress 4.0 cards can still be used in the Z6 but you won’t see any speed benefits in-camera. You will however benefit when copying files to your computer providing a 4.0 reader is used.
We strongly recommend using CFexpress Type B cards over the now older and slower XQD cards that many manufacturers are discontinuing.
Recording video in 4K UHD 30p (144 Mbps) requires a memory card that supports a minimum sustained write speed of 18 MB/s. All CFexpress cards will meet this requirement.
