A new, fairly expensive ENG-style camera that's only HD resolution? But it has the same sensor as the most sought-after camera in Hollywood (according to the Oscar nominations)!

Given that current 4K sensors are more than adequate to replace 35mm film in terms of sheer resolution, we need to be careful about turning this into a numbers game.
