Sony has introduced two 4K-capable modular cameras, including the PMW-F55 which has a Super 35-sized sensor with a global shutter. The specifications of the two cameras are pretty overwhelming – 16-bit Raw recording, parallel 2K and 4K recording, but the biggest news is the global shutter – the ability to capture all pixels simultaneously, rather than one line at a time – totally eliminating rolling shutter effect.
