Nikon will release firmware version 1.10 on Feb. 25.
According to Nikon, firmware version 1.10 for the Z7 II and Z6 II full-frame mirrorless cameras will be released on Feb. 25, unlocking Blackmagic RAW, better Eye-Detection AF, and other enhancements. Additionally, the Z6 II will record 4K UHD 60p, which is already available on the Z7 II.
To shoot BRAW, it requires the Z7 II and Z6 II to be sent to a certified Nikon facility to perform a hardware update. That cost is $199 +shipping. However, if you already purchased Nikon's RAW video upgrade for ProRes RAW, downloading the latest firmware version will give immediate access to BRAW when paired with Blackmagic Video Assist 12G HDR external recorders.
It's worth noting RAW recording isn't available across all sensor formats on the more robust Z7 II. The Z7 II records 4K UHD RAW in DX (24x16mm) only and full HD RAW in FX (36x24mm) only. However, the Z6 II will record RAW 4K UHD and full HD in both sensor modes.
- Z7 II: 4K UHD (DX format only), 1080p FHD (FX format only)
- Z6 II: 4K UHD and 1080p FHD (FX, DX formats)
With the update, the Nikon Z II series can externally record 12-bit RAW in both BRAW and ProRes RAW formats, the latter being supported by the Atomos Ninja V. Both external recorders also support Avid DNx, ProRes 422 LT, 422, or 422 HQ up to 4K 60p.
Blackmagic Design is expected to release its own Video Assist firmware update to support the Nikon Z II series around the same time that should support all constant bitrate and constant quality codecs from Bitrate 3:1 and Constant Quality Q5. Be sure to update to the latest firmware on the Video Assist when it becomes available.
If you're a Z7 and Z6 owner, Nikon has already released the necessary firmware to record ProRes RAW and Blackmagic RAW last year. You can download version 3.20 on the original models and Video Assist Update 3.3.1 to start recording BRAW.
