These are the new Sony FF sensors that can be used by Leica-Panasonic too
SonyAlphaRumors spilled out the info about the two future Full Frame sensors that will go on market in 2019. These sensors are NOT for exclusive Sony use. They will be available for any camera company. It means Leica and Panasonic could on paper decide to use them too. Sigma will not as they alreayd said they will make a Foveon sensor.
16 channels (which is crazy, normally it should be 8),
Maybe Leica will use that sensor on their future SL camera. Panasonic might launch a camera with the 60MP sensor in early 2020?
