Nikon just released firmware update 2.20 for the Nikon Z6 and Z7 Cameras providing CFexpress support and RAW video output:
CFexpress:
CFexpress cards are robust and reliable, and support even faster data transfer than XQD cards for a smoother and more efficient photographic workflow.
CFexpress cards use a similar form factor to XQD, eliminating the need to physically modify the camera’s memory card slot. After upgrading, users will be able to use CFexpress as well as XQD cards in their camera interchangeably.
RAW video output function (4K UHD and Full HD)
12-bit 4K UHD or full-HD RAW video can be recorded to select models of Atomos video recorders connected to a Z 7 or Z 6 camera via a HDMI connector. As RAW video is not subjected to in-camera processing, all information that is outputted from the image sensor is preserved. This abundance of information can later be used in post-production.
The RAW video output capability upgrade can be installed at a Nikon service center and will incur a fee.
