Thanks for the explanation, Akira. The Panasonic sensor and lenses tend to be pretty saturated and on the 'blue' (or cool) side. Is the the Dynamic range improved compared to the earlier GH1? And how do you feel it compares with the D750?
The pliability of D750 RAW file is far superior to that of GH5, of course. But I have always been impressed by Panasonic's metering technology to stuff the dynamic range of challenging scenes into the humble 12bit losslessly compressed RAW file from m4/3 sensors on all the bodies I have used (even from the very first G1, through GH2 and the very "lowly" GF5 and GX8).
The dynamic range has been improved over the years, and that of GH5 is definitely the pinnacle of the series at this point. As mentioned above, the pliability is limited, but the quality of the straight-out-of-the-camera image is already pretty admirable, so I don't feel limited. The D750 RAW file offered the noise performance and the dynamic range a 1.5-2.0 stop advantage over that of GH5. But that is made up for very well by the excellent image stabilization and the minuscule shutter shock which enables me to stay with lower ISO settings.
The hue seems to be no more on the cooler side. The waterfall leaves image looks cool in terms of the hue, because it was shot in the very cloudy daytime. The yellow color in general is less cyan than that of D750.
