The BMPCC 6K is featuring a Super 35 size sensor, 13 stops of dynamic range and dual native ISO up to 25,600.
The large 5 inch touchscreen also helps you to frame your 6K videos.
All of this with a EF-Mount... a great piece of gear.
My only minus points is the battery life and the internal stabilisation.
