A short test of the EOS C100 with canon 50mm/f1.4 (set to F2.8).
I started comparison of the canon-log gamma with ISO850 (where I set exposure by lens aperture to be "just without overexposure" on the waveform monitor with a small reserve headroom) to WDR gamma with ISO400, to cine1 gamma with ISO320 and to normal4 gamma (with knee on 90) with ISO320, all with the exactly the same exposure (I didn't change lens aperture or shutter speed or ND filter or amount of the light).
I find that all these gamma curves differ at black and the overall colors look but all of them is the same at exposure level ("...just without overexposure"). It is really interesting that canon-log don't look like a big 800pct exposure latitude vs. cine1 small 300pct exposure latitude but levels at black are better with log gamma and also differ overall tonal gradation and colors. For canon-log is ISO640 best setting for grading with minimal level of noise in black but cine1 with ISO320 is very nice with a very good colors.
