@Manu4Vendetta with settings used in these clips, the GH4 shows higher DR and a more appealing image (to my taste, of course). A7s looks to much contrasted. May be they did not use SLog-2 and native ISO.

Vodemort's comparison seems very biased to the A7s. The exposure has not been optimized for each camera. This undermines the significance of the conclusions. The colors are also very different. It is very obvious at 0:24 with the bluish green d…

@apefos with two fast consecutive short exposures at different ISO and/or speeds it would be possible, with some processing (that could be done asynchronously), to obtain almost the same result without hardware change. Magic Lantern did that for the…

Sure A7s is (will be) a fantastic camera, but I am not that excited with the extraordinary DR. I have no reason to doubt that it will have 15.3 stops of DR or even larger. It is possible. However I wander if that enormous DR will be really usable. W…
