>>3126619>keep the sensors that test the best for themselvesBut there re other reasons for this than you think.
Sony Semiconductor is a separate limb from Sony Imaging.
I'll give you second example. Sony Semiconductor can make sensor with Dual Pixel, and sell them to Samsung smartphones. Why? Because Samsung either has the technology licensed from Canon, or they don't give a fuck about Canon, and Canon doesn't have the balls to do patent war with Samsung.
But Sony Semi Conductor can't sell that sensor to Sony Imaging, because Sony Imaging doesn't have that license from Canon, or they don't care to buy that license from Canon.
