maybe off topic (or back to topic ?) seems D850 sensor is not made by Sony but by towerjazz ex panasonic

if they have the technology why don't they make a similarly capable 22 MP MFT sensor ?

 

They are working on totally new sensor technology, organic sensors. The idea is that wells of organic sensors have much larger well capacity, and hence better performance noise-wise, and higher iso possibilities .

 

Kind regards, Wim
