Tony Northrup compares the raw image quality of the Sony a9 III against the Canon R3. These popular sports photography cameras have different types of sensors: The Canon R3 has a stacked sensor while the Sony a9 III has a newer global sensor.
Tony Northrup compares the image quality at the base ISO of each camera, along with their dynamic range in recovered shadows. He then goes on to discuss why the a9 III has a worse dynamic range - it's a property of the construction of the photosites required to achieve the instant readout of the global shutter.
Next, Tony compares the high ISO performance of the two cameras at ISO 1600, ISO 6400 and ISO 25,600. He also compares the two camers after applying Adobe Lightroom Classic DeNoise. Finally, Tony compares the Sony a9 III against an APS-C camera to see if the image quality really is similar to a Fujifilm XH2.
