In addition to unveiling its full-frame cube cam BS1H, Panasonic also announced yesterday via press release that in the future the LUMIX GH5S as well as the LUMIX BGH1 will also be able to output Blackmagic RAW to Blackmagic Video Assist 12 HDR. This was previously only reserved for the large sensor models LUMIX S1H, S1, S5 and BS1H.
Furthermore, ProRes RAW output to supported Atomos recorders is of course possible with the MFT models. Which RAW dialect suits your workflow is ultimately determined by the editing, grading or compositing system you use.
The output for both RAW dialects is always in 12 bit. At 59.94Hz system frequency, three possible frame rates are available in 4K 4096 x 2160 (17:9) or in Anamorphic 3.7K 3680 x 2760 (4:3): 59.94p, 29.97p, 23.98p.
At identical resolutions, 50.00p and 25.00p are possible at 50 Hz system frequency. Exact 24.00p is obviously not implemented.
Since the BGH1 does not have its own display or viewfinder, an additional function was implemented in the new firmware: Because you would otherwise have to connect another monitor for camera operation, you can alternatively switch the RAW output on and off by an external key combination. This way, the used RAW recorder can still be used to operate the BGH1.
In addition, manual fine adjustment of the focus rings on the lens becomes possible with the new firmware. In addition to linear and nonlinear behavior, the path of the focus control can now be set individually from 90 to 1080 degrees. This will be possible not only on the GH5S and BGH1, but also on the G9 with new firmware.
However, you still have to be patient, the new firmware versions V2.2 (GH5S), V2.3 (BGH1) as well as V2.5 (G9) will only be available as a free download from November 4, 2021 at 3:00h.
