At ISO25,600does the new Lumix S1 outperform GH5S ISO TEST

Is the full-frame Lumix S1 a better low-light camera than the GH5S? I've conducted an ISO test between these three Panasonic cameras—GH5, GH5S and S1. After reviewing the footage, these are the top ISO settings I'm comfortable shooting with on each camera: GH5 ISO1600 GH5S ISO12800 S1 ISO25600 See the full list of equipment I use: #LumixS1 #ISO
