                The Sony A7 III uses all the pixels on the sensor to 'oversample' the video and then downsize it to 4K resolution. This oversampling offers the best image quality. The higher resolution sensor in the Sony A7R III captures too much data for the camera's processor to oversample it down to 4K.Nov 12, 2021
