Atomos is enabling more and more cameras to record externally in ProRes
RAW using its monitor-recorder combo
Ninja V. After Atomos recently added ProRes
RAW recording to
Panasonic Lumix S1H,
Sony Alpha 7S III and
Z CAM, a beta pre-release of the Ninja V AtomOS v10.53 firmware is now available, enabling 12-bit 4K ProRes
RAW recording with the Fujifilm GFX100 and ProRes
RAW recording (at up to 120 fps) with Sigma fp. Atomos V owners can register at
Atomos register to download the pre-release of the new firmware.

The Atomos update gives the small full format camera
Sigma fp the ability to record externally via HDMI

For comparison: up to now the Sigma fp has mastered the internal recording of 4K/UHD with max. 30 fps or FullHD
with max. 120 fps (MOV). On an external SSD connected via USB 3.1, CinemaDNG can also be recorded: in 4K 12bit with max. 24fps, in 10bit with max. 30fps, FHD in 12bit with max. 60fps. RAW recording is also possible internally on SD card, but in 4K resolution only with 8bit (FHD with 12bit).
