4K is not even properly here yet, considering my wife hasn't bought me a 4K-capable screen yet, and now were hearing about not only 8K cameras, but 8K cameras capable of capturing 120Hz.
Normally they capture at 60Hz, but 120Hz would make motion on screen look silky smooth, and not just for sport, but for movies, games and more. The Japanese Broadcasting Corporation's latest model was on show at IBC in Amsterdam, showing off the 120Hz, 8K-capable camera's abilities.
Engadget was there for some eyes-on action, citing that when "Filming a rotating image that paired ordinary objects and cityscapes with letters and numbers, you could see the difference instantly, with the 120Hz image on the right side yielding far shaper details, while the left side was often a blurry mess."
I'm a huge advocate of 120Hz, as I use only 120Hz displays at home right now. But, they're limited to just 1920x1080. I want some 2560x1xx0-capable monitors, but there's nothing in 120Hz (in quality, there are cheap alternatives, however).
