The Dalsa Origin was the original digital cinema camera that offered 4K resolution. Despite its whale-like size, there seems to be nothing but good things said about it’s image and dynamic range.
NHK (an extremely forward thinking Japanese broadcasting company) requisitioned Dalsa (at the time, early 2000s, they were/are a premier semiconductor designer)  to design them a sensor that met the 4K x 2K resolution requirements. Only Dalsa kept the intellectual rights and then used the sensor to make it’s own camera from the ground up. It was to much to early, and “too big”.
