According to Film and Digital times Sony is planning to show the prototype of a new >4K motion picture camera at NAB 2011.
It doesn’t have a name yet, but instead of calling it the Next CineAlta Camera, let’s give it the working title of Cine Altissima. She is not a mere 4K motion picture camera. Behind the PL mount, there’s an 8K sensor: 8768 x 2324 pixel single CMOS sensor (that’s 20.4 Megapixels) — Super35 3-perf size, 16-bit RAW output, 16:8:8.
In normal mode, Sony 4K camera will shoot from 1-72 fps. In High Frame Rate mode 1-120 fps.
