The Sony a7S III seems still not near for official announcement, we expect this camera will be officially announced in early 2020 at the earliest. According to latest rumors, the Sony a7S III will shoot 4K video at 120p and have a cooling fan.
In a recently interview with Sony manager by ImagingResource at Sony a7R IV (B&H Photo Video/Adorama/Amazon) launch event, Sony manager said a7RIV doesn’t do 4:2:2 10-bit internally because of the sensor and type of camera, but it can do 4:2:2 with an external recorder. Sony manager also confirmed again that Sony is currently working on internal 10bit 4:2:2 and 4K 60p to next Sony cameras (Most likely the long awaited Sony a7S III).
