Yea exactly. Hard to use a fixed screen for video nowadays. And the RF mount would make the variable ND adapter available for EF lenses (though I like the RF versions much more and most are packing IS). But man, everything else in the 1DX III outside of its overall size is near perfect. Even with that size it is tempting due to the impressive battery life. Let's see when all the other specs are released, but Canon seems to be moving in the right direction quickly.
