In the video I compare the low-light quality of the Lumix GH5, Olympus OMD EM1 II, Fujifilm XT2 and Sony A7s II in 4k 25p at 1600 ISO to their maximum movie sensitivities of 12800, 6400, 12800 and 409600 ISO respectively. Each camera was set to the same colour temperature and using its standard profile. I used lenses which delivered roughly the same field of view and adjusted the distances where necessary – the Sony samples look different due to the perspective of a longer lens and bigger sensor. The lighting was fixed and the exposures matched at each sensitivity, so any difference in brightness here is due to processing styles and variations in actual sensitivity.
