Personally, I don't care about RS anyway so it's a non issue for my way of filming.
But some things feel rushed in a way that they made it more complex it needed to be. For example, you can use our dual native ISO but if you want DR Boost you now have new base ISO settings. It feels counter intuitive to calculate small things like that while shooting for a gig. In a way it reminds me of the GH6 when it came out, in which you had to film in 2000 ISO when using with DR Boost on. Then a year later the G9II comes out and its like "dude just set your ISO level and I will boost the DR for you no matter what".
And what's with the 120fps tops? Even my old S1 can shoot 180fps in FHD (crappy image but still).
However, they finally have no crop up to 4K60, the moire issues of the past are non-existent and the beefy colour rendering (subjective) coming out of the image is more than welcome. I like the fact that they stuffed in every little thing they could, with not much left to be desired.
I don't know/care if it's going to make Sony or Canon shooters swap, for me it's a safe upgrade path from the original S1 series.
